Laser Arrays Put Facial Recognition On Android Devices

Created by ams, the PMSIL embarks as a low-power IR VCSEL laser emitter, that is enabling the world’s first implementation of user face recognition in a smartphone based on the Android platform. The Mi8 Explorer Edition, the new flagship smartphone from the fast-growing Chinese brand Xiaomi, includes a face recognition system which uses infrared (IR) vertical cavity surface-emitting laser (VCSEL) arrays from ams. The PMSIL is a complete VCSEL flood illuminator system with integrated eye-safety interlock, offering very high optical efficiency and minimizing the drain on the phone’s battery when emitting.

 

The PMSIL incorporates the emitter die, and a diffuser in its compact 3mm x 3mm x 1mm package. It features high spectral stability over temperature, and a narrow spectral width of <1 nm. Its engineered beam profile can be precisely configured to the needs of specific smartphone applications.

Fierce AI Week

Register today for Fierce AI Week - a free virtual event | August 10-12

Advances in AI and Machine Learning are adding an unprecedented level of intelligence to everything through capabilities such as speech processing and image & facial recognition. An essential event for design engineers and AI professionals, Engineering AI sessions during Fierce AI Week explore some of the most innovative real-world applications today, the technological advances that are accelerating adoption of AI and Machine Learning, and what the future holds for this game-changing technology.

 

In the Mi8 Explorer Edition, the PMSIL operates in always-on mode for face detection and recognition. The IR VCSEL emitter in the structured lighting system, the CS115, is also supplied by ams. The IR emitter is an IR chip-on-substrate VCSEL array, and is also notable for its small footprint and high optical efficiency.  Additionally, ams supplies the TMD27253 ambient light sensor and proximity detection module in the Mi8 and Mi8SE models.
