Executive Summary

This full reverse costing study has been conducted to provide insight on technology data, manufacturing cost and selling priceof the Huawei’s 3D Depth Sensing System found in the Mate 20 Pro.

• The front optical hub packaged in one metal enclosure features several camera and sensors. The complete systems feature an RGB camera module, a proximity sensor and an ambient light sensor. The 3D depth sensing system comprise the NIR camera module, the flood illuminator and the DOT projector.

• This report will be focused on the analysis of the 3D depth sensing systems. All components are standard that can be found on the market. That includes a GS image sensor featuring 3 µm size pixels and standard resolution of 1.5 megapixel and two vertical cavity surface emitting laser (VCSEL), one for the DOT projector and one for the flood illuminator coming from different supplier. Both, camera and DOT projector uses standard camera module assembly with wire bonding and optical module featuring lenses. In order to provide the structured light features, a WLO is integrated to the DOT projector structure.

• This report analyzes the complete 3D depth sensing system, including a complete analysis of the NIR camera module, and the dot projector, along with cost analysis and price estimation for the system. It also includes a physical and technical comparison with other 3D sensing systems, such as those from Apple in the iPhone X, from Oppo in the Find X and from Xiaomi in the Mi 8 Explorer. The comparison looks at system integration, the NIR camera module and the dot projector architecture.
