Lextar Releases VCSEL Products to Target 3D Sensing Applications

Lextar has announced that it is going to launch a series of VCSEL products for 3D sensing applications including facial and gesture recognition, people detection, and driver fatigue detection.

Lextar’s VCSEL products include the PV88M component series which emit light for 3D depth-sensing module. The series provides various wavelengths, different levels of brightness and package sizes while offering a beam angle selection from 45 to 100 degrees. According to Lextar, the product can also be customized to meet the needs of its clients.

The company is going to showcase its VCSEL products and Mini LED module for automotive tail lamp in Electronica 2018. During the event, Lextar will present VCSEL products integrated in camera modules and application software, providing interactive experiences for visitors. For example, users can try using gesture to adjust audio volume or answer phone calls in a car.

The VCSEL series products are also capable of reading faces and distinguishing humans from photos, which is critical for security system applications. For human detection applications, it can recognize humans and detect human height for security monitoring of senior and children, as well as visitor control in public areas. Moreover, it can detect reactions such as closed eyes and nodding with its driver fatigue detection function to enhance driving safety.

According to Lextar, the current mainstream applications of 3D sensing include stereo vision, structured light, and ToF (Time of Flight). Lextar has begun shipping its VCSEL products to several mobile phone manufacturers since 3Q18.
