STMicroelectronics VL53L5CX 8×8 Multi-Zone Time-of-Flight Sensor integrates a SPAD array, physical infrared filters, and diffractive optics (DOE) in a miniature reflowable package. The VL53L5CX offers multi-zone distance measurements with up to 8×8 real-time native zones and a wide 63° diagonal field of view. Each zone of the sensor allows measuring the distance to a target at 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.
These features allow the VL53L5CX to achieve the best ranging performance in various ambient lighting conditions with various cover glass materials. The use of a DOE above the vertical-cavity surface-emitting laser (VCSEL) enables a square FoV to be projected onto the scene. The receiver lens focuses the reflection of this light onto a SPAD array.
The STM VL53L5CX 8×8 Multi-Zone Time-of-Flight Sensor utilizes a direct ToF technology that allows absolute distance measurement, whatever the target color and reflectance. The ToF technology provides accurate ranging up to 400cm, and the 32bit MCU with extra HW accelerator can post-process the histogram and stream ready-to-use depth information at fast speeds (60Hz).
