6 RIEGL VUX -1 with Additional Equipment Cooling Fan Device Lightweight structure with two axial fans providing forced air convection for applications where sufficient natural air flow cannot be guaranteed. Power supply is provided via a connector on the rear side of the RIEGL VUX-1. The cooling fan device can be mounted either on the top side or on the bottom side of the RIEGL VUX-1 and is included in the scanner s scope of delivery. The cooling fan device is to be mounted whenever the environmental conditions/temperatures require (see temperature range on page 2 of this datasheet). RIEGL VUX-1 with Protective Cap Multiple-Time-Around Data Acquisition and Processing Field of View (FOV) 33 MTA 1 MTA 2 RIEGL VUX-1 with external IMU-Sensor (optional) In time-of-flight laser ranging a maximum unambiguous measurement range exists, which is defined by the laser pulse repetition rate and the speed of light. In case the echo signal of an emitted laser pulse arrives later than the emission of the subsequently emitted laser pulse, the range result becomes ambiguous - an effect known as Multiple-Time-Around (MTA). The RIEGL VUX-1 allows ranging beyond the maximum unambiguous measurement range using a sophisticated modulation scheme applied to the train of emitted laser pulses. The dedicated post-processing software RiMTA provides algorithms for multiple-time-around processing, which automatically assign definite range results to the correct MTA zones without any further user interaction required.
