VL53L5CX – Time-of-Flight 8×8 multizone ranging sensor with wide field of view from STMicroelectronics

 

VL53L5CX is a first real time native 8×8 multi-zone Time-of-Flight sensor with wide field-of-view, multi-target detection and distance measurement for each zone. Multi-zone distance measurements are possible up to 8×8 zones with a wide 63° diagonal field of view. The sensor provides an accurate ranging up to 4 meters, with a maximum frequency of 60Hz. With ST’s patented histogram algorithms, the VL53L5CX detects multiple objects within the FoV and ensures immunity to cover glass crosstalk beyond 60cm.

Technology

VL53L5CX offers multi-target detection and distance measurements in each zone at up to 4 meters. Housed in a minature reflowable package, it integrates a SPAD array, physical infrared filters, and Diffractive Optical Elements (DOE) to achieve the best ranging performance in various ambient lightning conditions.

VL53L5CX uses ST’s lastest generation, direct ToF technology which allows absolute distance measurement regardless of the target color and reflectance. It can work at fast speeds (60Hz), which makes it the fastest, multizone, minature ToF sensor on the market.

Multi-zone resolution

The use of a DOE above vertical cavity surface emitting laser (VCSEL) allows a square FoV of 45°x45° (63° diagonal) to be projected onto the scene. The reflection of this light is focused by the receiver lens onto a SPAD array.

The VL53L5CX can range up to 8×8 zones at 15Hz for higher resolution or use 4×4 zones at 60Hz for faster ranging measurements. The sensor is also able to detect multiple objects in the FoV.

VL53L4CX – long-range, multitarget measurements

The VL53L4CX provides very accurate distance measurements up to 6m with excellent results over short distances. A new generation laser emitter with 18° FoV improves performances under ambient light. As well as VL53L5CX, 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 ToF sensors based on ST’s FlightSense technology, the VL53L4CX records an absolute distance measurements regardless of the target color and reflectance.
