Executive Summary
This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling price
of the Orbbec 3D sensing system found in the Oppo Find X.
• Located in the Find X’s front, around the speaker, the optical hub is packaged in one metal enclosure. It has several modules
like a DOT projector, a Red/Green/Blue Camera, a flood illuminator, an ALS/Proximity sensor and a NIR camera Sensor. An
additional SoC component is soldered on the main board to process the signal from the latter devices. Separated into two
dimensions, the optical hub has a flood illuminator, an RGB camera and a proximity sensor for the 2D sensing and a NIR
camera and DOT projector for the 3D sensing. This report will be focused on the 3D sensing system.
• With standard component found on the market, a GS Image sensor featuring 3 µm pixel size and standard resolution of 1
MP and a VCSEL, the system is very cost efficient compared to other solutions. The camera and dot projector module
assembly use standard wire bonding to connect the sensor or the VCSEL dies, along with an optical module comprising four
lenses for both modules. In order to structured the light, a special mask unlike a DOE system is used to give a dot pattern.
• This report analyzes the complete 3D sensing system, including a complete analysis of the NIR camera module, the DOT
projector and the SoC, along with a cost analysis and a price estimation for the system. It also includes a physical and
technical comparison with other 3D sensing system, such as those from Apple in the iPhone X facing the system integration,
the NIR camera module and the DOT projector architecture. Finally, to give an idea of the complete optical hub cost and
compare it to other systems, the complete 3D sensing systems cost is estimated.
