Description

The VL53L0X is a new generation Time-of-Flight (ToF) laser-ranging module housed in the smallest package on the market today, providing accurate distance measurement whatever the target reflectances, unlike conventional technologies. It can measure absolute distances up to 2m, setting a new benchmark in ranging performance levels, and opening the door to various new applications.

The VL53L0X integrates a leading-edge SPAD array (Single Photon Avalanche Diodes) and embeds ST's second-generation Flight SenseTM patented technology.

The VL53L0X's 940 nm VCSEL emitter (Vertical-Cavity Surface-Emitting Laser), is totally invisible to the human eye, coupled with internal physical infrared filters, it enables longer-ranging distances, higher immunity to ambient light, and better robustness to cover glass optical crosstalk.

Applications

• User detection for personal computers/laptops/tablets and IoT (energy saving)
• Obstacle detection with Robots (Robotics)
• White goods (hand detection in automatic faucets, soap dispensers, etc.)
• 1D gesture recognition
• Laser-assisted autofocus. Enhances and speeds up camera autofocus system performance, especially in difficult scenes (low light levels, low contrast) or fast-moving video mode
