VCSEL Application 1 3D Sensing
3D sensing is usually composed of a camera and a depth sensor, and obtains the depth information of an object by projecting a specific wavelength band to calculate the time difference between light emission and reflection. 3D sensing technology realizes the acquisition of real-time three-dimensional information of objects, which provides key features for later image analysis. Smart devices can restore the real three-dimensional world based on 3D sensing and realize subsequent intelligent interactions. The current market applications are face recognition, lidar, AR/VR, etc.
3D camera, with dozens of functions such as face recognition, gesture recognition, human skeleton recognition, 3D measurement, environment perception, 3D map reconstruction, etc., can be widely used in TV, mobile phone, robot, drone, logistics, VR/AR, Smart home security, car driving assistance and other fields

Face recognition
Face recognition can be used in electronic fields such as mobile phones, face payment, and smart door locks. Compared with traditional methods, 3D face recognition has the advantage of reducing the impact of ambient light changes on face detection and recognition; preventing photos, videos, etc. Misidentification, improve the security of face recognition. KT Photonics provides VCSEL chips for 3D face recognition applications.
