The new pmd/Infineon REAL3 imagesensor, reference IR 2381C, offers morethan simple face authentication for the LGG8 ThinQ smartphone. The indirect Time-of-Flight (ToF) camera and the floodilluminator allow face recognition, andalso the recognition of the palm veinpatterns. Moreover, the ToF module isused for the new ‘Bokeh’ smartphonephotography mode. Bokeh allows users totake pictures without blur in real-time.Lastly, the new indirect ToF module allowsusers to interact with the phone withouttouching it, using hand gestures.

The ToF Module in the LG G8 smartphoneis based on the REAL3 image sensor, aNear Infra-Red (NIR) sensor and a floodilluminator, using a new-generationVertical Cavity Surface Emitting Laser(VCSEL) die from ams AG. The totalsolution is designed by pmd.

This report is focused on the analysis ofthe 3D depth-sensing camera, comprisingthe NIR ToF camera module with REAL3CMOS and the flood illuminator. This newNIR image sensor is 40% smaller than the2016 module from Lenovo Phab2Pro, withthe same 224x172 pixel definition. This iscoupled with the new generation of theVCSEL laser die from ams AG, which is12% smaller than the last generation. Thenew VCSEL electrode has been re-designed, and the cavity diameterreduced by 15%.

This report analyzes the complete 3Dindirect ToF camera, provided along withcost analysis and price estimation for themodule.

It also includes a physical and technicalcomparison with other 3D camerasystems, such as the pmd/Infineon ToFimage sensor in the Lenovo Phab 2 Pro,and the Panasonic MN34906 charge-coupled device (CCD) ToF image sensor inthe Vivo Nex Dual Display. Thecomparison looks at system integration,the NIR camera module and theilluminator architecture.
