描述 Description

Specifically designed for long-range, multitarget measurements, the VL53L4CX provides very accurate distance

measurements up to 6 m with excellent results over short distances. A new generation laser emitter with 18° FoV

improves performances under ambient light.

Thanks to ST's patented algorithms and innovative module construction, the VL53L4CX is also able to detect

multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk

immunity beyond 80 cm and dynamic smudge compensation for targets below 80 cm.

Like all Time-of-Flight sensors based on ST's FlightSense technology, the VL53L4CX records an absolute

distance measurement regardless of the target color and reflectance.

Housed in a miniature reflowable package, which integrates a SPAD (single photon avalanche diode) array,

the VL53L4CX achieves the best ranging performance even when hidden behind a wide range of cover glass

materials.

All of ST's Time-of-Flight sensors integrate a VCSEL (vertical cavity surface emitting laser) which emits a fully

invisible 940 nm IR light, which is totally safe for eyes (Class 1 certification).
