3 E Physical asics for Structorized Illumination lines primarily are characterized by their length and their working distance. Depending on measurement requirements, further parameters are relevant. The measurement resolution is given by the line width but limited by speckle. In case of measurement objects with expanded height a sufficient depth of focus has to be accounted for. SchäfterKirchhoff supplies two types of laser lines which are adapted to different measurement requirements, laser micro lines with small line width and laser macro lines with extended depth of focus. Depth of Focus of a The laser lines are focussed to a defined working distance. t deviating distances the lines broaden and the power density drops. The range around the nominal n additional criterion for the selection of a laser line is the fan angle. for measurements on objects with glossy surfaces SchäfterKirchhoff supplies semitelecentric laser lines. spot generators are characterized by spot size and depth of focus. gain SchäfterKirchhoff supplies micro focus generators with low spot size and macro focus generators with extended depth of focus. working distance, in which the laser line does not increase by more than a factor., is usually specified as depth of focus of the laser line. The depth of focus is calculated differently for the two laser line generator types. Width To increase the power density on the sensor, a preferably thin laser line should be used if the laser power available is small. To increase the measurement accuracy, subpixelalgorithms can be used with thicker laser lines, if disturbances by laser speckle (see below) are small. Micro s and Micro Focus Micro Generators (see fig. ) generate thin laser lines with high power densities in the focal plane. They are suitable for measurements with high spatial resolution. Perpendicular to the laser line, laser micro lines have a Gaussian intensity profile. The depth of focus of a laser micro line with width (measured at the.% level) and wavelength λ is given by the rayleigh range z r Rayleigh range z r = p λ Macro s and Macro Focus Macro Generators generate laser lines with extended depth of focus. t the same working distance, laser macro lines are thicker than micro lines (factor ). Within the depth of focus range, the intensity profile perpendicular to the laser line also is approximately Gaussian. side lobes appear beyond the depth of focus range. The depth of focus range z M. of a macro laser line is approximately given by. z M =. p λ. Z r The side lobes caused by diffraction remain below the.% intensity level with in the depth of focus range (fig.). t the same working distance, laser macro lines have a to times larger depth Z r Depth of focus Z r. Within the two types micro and macro line generators the width of the laser line is proportional to the working distance. With increasing distance from the nominal working distance and increasing line width, the power density decreases. since there is a fixed physical relationship between the width and the depth of focus of a laser line, the depth of focus required by an application also determines the minimum laser line width. Micro Focus Generators similarly, laser micro focus generators generate laser spots with high power density and Gaussian intensity profile. The same formula is used for the rayleigh range, the line width being replaced by the beam diameter Ø. Density of focus than laser micro lines. This is due to the increased line width and the factor.. The output power of laser macro line generators is generally smaller (%) than the output power of laser micro line generators. Macro Focus Generators: macro focus generators generate laser spots, which are larger than laser micro spots and which also have an extended depth of focus. Density % % % % % % µ m...

Working range increased by a factor of (compared to fig. ). linien_prosp_e_.indd Page Speckle speckle are interference effects, caused by the coherence of the laser radiation, which arise, e.g., from laser illumination of a rough surface. speckle disturb the edge sharpness and homogeneity of laser lines. orthogonal to the laser line, the center of intensity is displaced stochastically. The granularity of the laser speckle depends on the aperture setting of the lens used to image object and laser line onto the sensor. With a small fnumber the arising speckles have a high spatial frequency, with a large fnumber the speckles are rather rough and particularly disturbing (see fig. ). s a diffuse reflective and thus an optically roughtextured surface is essential for the utilization of the laser light section method, laser speckling is not to be avoided in principle. reduction of the effect is possible by Diminishing the speckle pattern by choosing large lens apertures (small aperture numbers), as long as this is permitted by the requirements on the depth of focus, (see fig ). relative movement between object and sensor, possibly using an anyway necessary or existent movement of the sensor or the object (i.e. profile measurement of railroad tracks while the train is running). Use of laser beam sources with decreased coherence length (i.e. superluminescent diodes) Figure : D profiling by laser light sectioning Effect of lens aperture setting on laser speckling Measurement object with generated laser line and, incident angle, object illuminated by an additional dome illuminator object imaged with large aperture, f/#. C object imaged with small aperture, f/# for further information: The aperture of the imaging lens acts as a spatial frequency filter. With small fnumbers the speckle pattern appears to be less disturbing due to a high spatial frequency. With a large fnumber speckling introduces cuts and gaps in the contour of the line.

10 E Pattern Generator P... Diffractive beam shaping is based on diffraction at periodical and nonperiodical microstructures (synthetic hologram). The diffractive optical elements used by SchäfterKirchhoff are multilevel or ous phase structures with high transparency. They generate line patterns of finest structure like grids, circles, crosses, or multiple lines. The grid sizes, diameters, or line distances specified in table are valid for the standard working distance of the beam shaping optic. Different working distances within the given focussing range can be achieved by refocussing. The size of the generated patterns then changes approx. proportionally to the working distance.

In principle, all diffractive beam shaping optics show small deviations from the geometrical ideal (distortion). In applications like D profile measurements cali bration techniques are used to account for pattern distortion. The diffractive optical elements used by SchäfterKirchhoff have a high diffraction efficiency. The desired pattern contains approximatly % of the laser power. The residual laser power appears as undiffracted central spot (th diffraction order) in the center of the pattern.

Figure n automatic shutdown system (e.g., a door switch) has to be used for immediate disconnection of the interlock chain to prevent exposure of an unprotected person to hazardous laser radiation. The interlock mechanism in the SchäfterKirchhoff laser beam sources requires no external power supply.

13 E at Work Goggles Function and Characteristics Protective function Two different protective functions of laser safety goggles have to be distinguished, full protection goggles and alignment goggles. Full protection goggles according to European standard EN provide personal protection against laser radiation. The laser radiation normally is blokked and no longer visible. levels (protection level..) differ in the maximum spectral transmission of the filter glasses. In addition, the standard EN specifies a maximum power density (power devided by area, in W/m ) which is allowed to reach the filter glass. safety and laser adjustment goggles The use of laser safety goggles is recommended for work with lasers from laser protection class r on, e.g. all visible lasers from SchäfterKirchhoff with an output power up to mw. safety goggles are mandatory from protection class on, e.g. for all invisible infrared lasers and all visible lasers with more than mw output power from SchäfterKirchhoff. The correct handling and use of the laser safety goggles protects you and your colleagues against injuries of the eyes due to hazardous laser radiation. selection of ce and Gs certified laser safety goggles lignment protection goggles according to European standard EN attenuate visible laser radiation (wavelength nm) down to the power of a laser of class (EN ). The laser radiation remains visible, so that alignment protection glasses can be used for adjustment tasks. The protection levels (protection level r..) differ in the maximum power (in Watt) of a collimated laser beam which is allowed to reach the goggles. Maximum power (EN ): maximum power of a laser beam in the specified wavelength range which is sufficiently attenuated by the alignment protection goggles (acc. to EN ). are available (manufactured by Vision, www. lvg.com) for the lasers provided by SchäfterKirchhoff. Two different protective functions of laser safety goggles have to be distinguished, full protection goggles and alignment goggles. Depending on filter type two different frames are supplied. safety goggles with glass filters have a frame for which an adapter frame (order code R) for individual glasses is available. safety goggles with plastic filter are more lightweight and can be worn together with glasses. Maximum transmission (EN ): maximum transmission (minimum attenuation) in the specified wavelength range (acc. to EN ). Maximum power density (EN ): maximum power density the filter glasses can withstand over a longer period (acc. to EN ) VT: (visible light transmission): in addition to the specified wavelengths, laser protection goggles also attenuate the ambient light. The VT is the percentage of the daylight transmitted. OD (optical density): logarithmic scale for the attenuation of a laser beam at the specified wavelength.

14 E IR Detection Card IR Detection Card SKR eft: active sensor area right: plot of spectral sensitivity IR Reflection Invisible infrared radiation in the range nm or nm is converted to visible light by luminescence. The luminescence in the active detector layer indicates the position and approximate size of the beam. The detector cards should not be used for measurement tasks like the quantitative determination of the beam diameter. With, e.g., high power lasers, also the border area of the beam with less than < % of the intensity maximum will be visible, additional widened by scattering processes in the detector layer. on the other hand, of a low power beam only the central area will be shown. Detector cards of series sk...r diffusely reflect the luminescent radiation at the active layer. These cards are impermeable for the beam. Detector cards of series sk...t are transparent.

15 E pplications D Profiling of a railway track with laser macro line generators RM... and and CMOS matrix camera image of laser line recorded with camera image of laser line recorded with camera ight Section a key feature in D laser measurement techniques light sectioning is a D procedure to measure object profiles in a sectional plane. The principle of the laser triangulation (see Fig. ) requires an orthogonally to the objects surface positioned area camera (CCD or CMOSmatrix) to measure the lateral displacement or the deformation of a laser line projected in an angle onto the object surface. The elevation profile of interest is calculated from the deviation of the laser line from the zero position. Measuring range and resolution are determined by the triangulation angle between the plane of the laser line and the optical axis of the camera (see Fig. ). The more grazing this angle, the larger is the observed lateral displacement of the line. One requirement for the utilization of the laser light section method is an at least partial diffusely reflecting surface. To ensure a widely constant signal amplitude on the sensor, the depth of focus of the camera lens as well as the depth of focus of the laser line generator has to cover the complete measurement elevation range. The accuracy of the laser light sectioning is mainly restricted by laser speckle, an inter ference phenomenon originating from the coherence of the laser radiation. Speckle stochastically displace the center of intensity across the laser line. detailed discussion of this measurement technique, the basic principles, influencing variables and optimisation potentials can be found in the application report. Triangulation ( ight Section) h Camera Triangulation angle = high resolution, small measuring range (h) Figure : triangulation (optical scheme) The object height is calculated from the displacement of the laser beam incident with angle on the object surface. h Triangulation angle = reduced resolution, large measuring range (h) et there Shadow a.. b. diffraction measurement system for diameter, geometry, and edge position collimated laser beam is projected onto a CCD line scan camera. n object introduced into the laser beam shadows part of the laser beam. Directly and without intermediate imaging one or more shadow edges with superposed Fresnel diffraction patterns form on the linescan sensor. With thresholding high measurement frequencies in the kilohertz range are reached at a spatial resolution in the order of a camera pixel size. Evaluation of the Fresnel diffraction pattern leads to high spatial resolutions down two a few microns can be reached. The processing speed then depends on the computing power available.
