8 x 8 Multi-zone Time of Flight (ToF) ranging sensor

The VL53L8CX from stmicroelectronics is an 8 x 8 multi-zone time-of-flight (ToF) ranging sensor that improves performance in ambient light and reduces power consumption. Based on stmicroelectronics' FlightSense technology, the sensor provides accurate ranging up to 400 cm and a 65° diagonal field of view (FoV).

The VL53L8CX integrates a powerful new generation VCSEL and two advanced metasurface lenses. The hardware is installed in an innovative all-in-one module that supports a variety of high-performance use cases, such as low power system activation, gesture recognition, robotic SLAM, level monitoring, and more. Thanks to stmicroelectronics's proprietary algorithm, the VL53L8CX can detect and track multiple targets within a FoV, with 64-zone depth measurements.

The histogram ensures that the cross-talk immunity of the covered glass is above 60 cm. Like all ToF sensors based on Stmicro's FlightSense technology, the VL53L8CX measures absolute distance independent of target color and reflectivity. VL53L8CX supports SPI and I²C interfaces for high frequency frame rates and short startup times. The VL53L8CX VCSEL emits completely invisible infrared light at 940 nm, has Level 1 certification and is safe for the eyes

Applications

● Robot applications in complex environments include SLAM, wall tracking, small object detection, cliff prediction, and floor type recognition
● System activation under the light of intelligent building and intelligent lighting environment; For example, a user detects a wakeup device
● Content management for containers, trucks and garbage bins
● Liquid level monitoring
● Gesture recognition
● Keystone correction of video projector
● Devices that require better ambient light immunity
● Augmented reality/virtual reality augmented. Thanks to multi-zone distance measurement, dual camera stereo and 3D depth assist
● Internet of Things and battery powered devices for user and object detection
● Laser-assisted Autofocus (LAF) enhances the speed and robustness of the camera's autofocus system, especially in difficult low-light or low-contrast scenes
