STMicroelectronics VL53L5CX

VL53L5CX is a state of the art, Time-of-Flight (ToF), multizone ranging sensor. Housed in a miniature reflowable package, it integrates a SPAD array, physical infrared filters, and diffractive optical elements (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.

It uses ToF technology which allows absolute distance measurement whatever the target color and reflectance.
