Deep analysis of the rear 3D sensing module with Sony’s 2nd Generation CIS.

SP20484 -Sony 3D ToF Sensing CM Gen 2 (Note 10+)_3

In order to support its recently registered trademark ‘Make & Play 3D’, Samsung is equipping its smartphones with 3D sensing modules. The Galaxy Note 10+ has one in the back side. Samsung is using the latest generation of Sony Depth sensing Solutions’ Time-of-Flight (ToF) camera, which is unveiled in this report.

The rear optical hub is packaged in one metal enclosure and features several cameras and a flood illuminator. The complete system features a main red/green/blue camera, a Telephoto, a Wide-angle Camera Module and a 3D Time of Flight Camera. The 3D Depth sensing module has a unique compact packaged near infrared (NIR) flood illuminator with the Vertical Cavity Surface Emitting Laser (VCSEL) driver placed on bottom using a flex printed circuit board (PCB).

This report is focused on the analysis of the 3D depth sensing module. It includes a backside illumination (BSI) Time of Flight Image Sensor array featuring 5µm size pixels and 323 kilopixel VGA resolution developed by Sony Depth sensing Solutions. It has one VCSEL for the flood illuminator coming from a major supplier.

Along with the complete 3D depth sensing system teardown, this report includes a cost analysis and price estimation for the module. It also includes a physical and technical comparison with another 3D sensing system from Oppo Rx17 pro as well as the 3D sensing solution for the Samsung Galaxy S10. The comparison looks at module integration, the NIR ToF camera module and the Flood Illuminator architecture.
