STMicroelectronics VL53L8CX Multizone Time-of-Flight (ToF) Ranging Sensor
Detect and track multiple targets within the FoV
The VL53L8CX is an 8x8 multizone, ToF ranging sensor, which enhances performance under ambient light with a reduced power consumption. Based on STMicroelectronics FlightSense technology, the sensor is designed to provide accurate ranging up to 400 cm with a 65° diagonal FoV.
The VL53L8CX integrates a powerful new generation VCSEL, and two advanced meta-surface lenses. The hardware is housed in an innovative "all in one" module. This enables a wider variety of high-performance use-cases, such as low-power system activation, gesture recognition, SLAM for robotics, liquid level monitoring, and many more.
Thanks to STMicroelectronics' patented algorithms, the VL53L8CX can detect and track multiple targets within the FoV with a 64-zone depth measurement. The STMicroelectronics' histograms ensure that the cover glass crosstalk immunity is above 60 cm. Like all ToF sensors based on STMicroelectronics' FlightSense technology, the VL53L8CX measures an absolute distance regardless of the target color and reflectance.
