VL53L9CX

概要

The VL53L9CX is STMicroelectronics’ dToF 3D lidar all-in-one module, offering a high spatial resolution of 2.3 K zones. It features a 71° diagonal FoV, with 1° angular resolution across a 55° x 42° FoV. It also delivers accurate ranging from below 5 cm to 9 m.

The combination of long distance ranging and high resolution makes it ideal for applications such as people counting, content monitoring, gesture recognition, smart building, and more.

The VL53L9CX can stream full-resolution processed data at up to 100 Hz, making it one of the fastest, truly integrated dToF 3D lidar modules on the market. A dual-scan flood illumination strategy replaces traditional sequential dot scanning, enabling robust detection of small objects and edges while eliminating motion artifacts in fast-moving scenes. These two unique features make the device particularly suitable for SLAM, obstacle avoidance, and small object detection in robotics and drones.

The VL53L9CX consumes only 150 mW of typical system power and comes in a compact package that measures 12.8 mm x 6.1 mm x 4.6 mm. This device offers a cost-effective solution for many applications, which include AR/VR and battery-powered IoT devices. For outdoor use, it delivers excellent ranging performance even under strong ambient light and is compatible with various cover glass materials.

The VL53L9CX is completely calibration-free and a true “all-in-one” mini-lidar. It integrates a SPAD array, postprocessing SoC, two VCSELs, physical infrared filters, metasurface optical elements (MOE), and an embedded power management IC. Its reflowable design further simplifies integration into diverse systems, reducing both complexity and cost and enabling rapid deployment.

Available output data includes: depth, 2D IR (with and without active illumination), reflectance, and confidence. Depth data are output directly via MIPI or I3C interfaces, ensuring broad compatibility with a wide range of CPU architectures.

The two VCSELs of the VL53L9CX emit fully invisible 940 nm IR light. Certified as Class 1 laser-safe, the device incorporates multilevel laser-safety checks that ensure eye safety and reliable operation.
