STMicroelectronics VL53L9 Direct Time-of-Flight (dToF) LiDAR Modules

STMicroelectronics VL53L9 Direct Time-of-Flight (dToF) 3D Light Detection and Ranging (LiDAR) Modules feature true all-in-one, easily integrated modules with up to 2.3k zones, ideal for smartphone camera assist and augmented/virtual reality (AR/VR) applications. The VL53L9 modules contain a single photon avalanche diode (SPAD) array, postprocessing SoC, two vertical-cavity surface-emitting lasers (VCSELs), physical infrared filters, metasurface optical elements (MOEs), and an embedded PMIC. The modules provide accurate ranging from <5cm to 10m and stream a postprocessed 2D IR image with a 60Hz max frame rate. Using the MOE above the VCSELs allows the user to project an optimized rectangular field-of-view (FOV) onto the scene. The STMicroelectronics VL53L9 dToF 3D LiDAR Modules achieve improved ranging performance with various cover glass materials. The modules are capable of multizone distance measurements up to 54 x 42 zones with a wide FOV.
