Product overview
Description
The VL53L9CA is a state of the art, dToF 3D lidar (light detection and ranging) module with market leading resolution of up to 2.3k zones enhancing the ST FlightSense product family. Housed in a miniature reflowable package, it integrates all necessary components to make it a true all-in-one and easy to integrate module. The VL53L9CA includes a SPAD array, postprocessing SoC, two VCSELs powered by a dedicated BCD VCSEL driver providing a flood illumination, physical infrared filters, metasurface optical elements (MOE), and an embedded PMIC. The module is Class 1 laser safe, offering skin protection in addition.
The use of a MOE above the VCSELs allows to project an optimized rectangular FoV onto the scene. The receiver lens focuses the reflection of this light onto the SPAD array.
Unlike conventional IR sensors, the VL53L9CA uses ST's latest generation BSI stacked direct ToF technology, which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging from below 5 cm up to 10 m. The VL53L9CA can stream processed data at maximum frame rate (60Hz), which makes it the fastest, truly integrated 3D lidar camera module on the market. Available output data: depth, 2D IR with active illumination, 2D IR without active illumination, reflectance, and confidence.
The VL53L9CA achieves the best ranging performance, including under strong ambient light conditions, with a range of cover glass materials. Multizone distance measurements are possible up to 54 x 42 zones with a wide 54°x42° FoV, which can be reduced by software.
