Description
The VL53L3CX is the latest Time-of-Flight (ToF) product from STMicroelectronics and embeds ST’s third generation FlightSense patented technology. It combines a high performance proximity and ranging sensor, with multi target distance measurements and automatic smudge correction. The miniature reflowable package integrates a single photon avalanche diode (SPAD) array and physical infrared filters to achieve the best ranging performance in various ambient lighting conditions, with a wide range of cover glass windows.

APPLICATION
• Service robots and vacuum cleaners (wall following and fast obstacle detection)
• Sanitary (robust user detection whatever the target reflectance)
• Smart buildings and smart lighting (user detection to wake up devices)
• IoT (user and object detection)
• Laser assisted autofocus (AF): enhances the camera AF system speed and
robustness, especially in difficult scenes (low light and low contrast); ideal
companion for phase-detection autofocus (PDAF) sensors.
• Video focus tracking assistance
