概要

The VL53L5 is a state of the art, Time-of-Flight (ToF), laser-ranging sensor enhancing the ST FlightSense product family. Housed in a miniature reflowable package, it integrates a SPAD array, physical infrared filters, and diffractive optics (DOE) to achieve the best ranging performance in various ambient lighting conditions with a range of cover glass materials. The use of a DOE above the vertical cavity surface emitting laser (VCSEL) allows a square FoV to be projected onto the scene. The reflection of this light is focused by the receiver lens onto a SPAD array.
Unlike conventional IR sensors, the VL53L5 uses ST's latest generation, direct ToF technology which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging up to 400 cm and can work at fast speeds (60 Hz), which makes it the fastest, multi-point, miniature ToF sensor on the market.
With patented algorithms and ingenious module construction, the VL53L5 is also able to detect different objects within the FoV with depth information at 60 Hz.
Scene browsing and multi zone detection is possible with the VL53L5 thanks to a software customizable detection array to achieve a quicker touch-to-focus or mini depth map.
