VL53L8CA

概要

The VL53L8 is a state of the art, 2nd generation, multi-zone Time-of-Flight (ToF), laser-ranging sensor enhancing the ST FlightSense™ product family. Housed in a miniature reflowable package, it integrates a SPAD array, enhanced VCSEL, physical infrared filters, and ST’s latest meta-surface optical technology to achieve the best ranging performance in various ambient lighting conditions with a range of cover glass materials. The use of a diffractive optical element above the 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.

This 2nd generation product offers half the typical power consumption or twice the ranging performance compared to the previous generation.

Unlike conventional IR sensors, the VL53L8 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). The enhanced design makes it the most power efficient, high performance, multi-point, miniature ToF sensor on the market.

With patented algorithms and ingenious module construction, the VL53L8 is also able to detect multiple objects within the FoV with depth information for quicker touch-to-focus or mini depth map creation.
