Executive Summary o Executive Summary o Reverse Costing Methodology o Glossary The Apple iphone X brings totally new functionality based on the TrueDepth technology. This project is issued from a collaboration including Lumentum for the VCSEL diode and Heptagon for the active DOE and folded optic. The iphone X implements this technology using a Dot Projector. The subsystem features a 30,000 dots projector from Heptagon. We estimate that the Active DOE and the folded optic are manufactured by Heptagon. The electronic package is assembled by an OSAT. The IC driver is designed by Broadcom. The nogrid VCSEL array diode is manufactured by Lumentum. Heptagon performs the assembly of the Dot Projector. To provide the 30,000 dots, the VCSEL supplies the IR light and the Folded Optic directs the IR light to the Active Diffractive Optical Element (DOE). Finally, the Active DOE divides the light beam into 30,000 dots of light. The VCSEL is driven in power, beam shape and frequency by an ASIC from Broadcom. The report includes technology and cost analysis of the Dot Projector. These analyses provide the technical intelligence necessary to understand this technology. A comparison between the Dot Projector and the Intel Real Sense projector and the PMD/Infineon solution are performed. 2017 System Plus Consulting Apple iphone X 3D Dot Projector 3
