Sony AS-DT1 3D LiDAR Depth Sensor, Compact, 40m Range, dToF SPAD

Smallest and Lightest Miniature Precision LiDAR Depth Sensor

The Sony AS-DT1 LiDAR Depth Sensor employs direct Time-of-Flight (dToF) technology combined with a Single Photon Avalanche Diode (SPAD) sensor array to deliver high precision 3D distance measurements. It outputs 576 ranging points per frame arranged in a 24 x 24 grid, enabling detailed depth mapping with a distance resolution of 0.98 inches. The sensor operates at up to 30 frames per second (fps) in normal mode and 15 fps when measuring at maximum range, allowing for smooth, real-time depth sensing in dynamic environments. The laser emits light at a wavelength of 940 nm, ensuring accurate ranging indoors up to 40 meters (131 ft) and outdoors up to 20 meters (66 ft).

Encased in a lightweight, durable aluminum alloy housing, the AS-DT1 measures only 1.14″ wide by 1.14″ high by 1.22″ deep, and weighs a mere 1.1 ounces. It features dual USB-C ports for high-speed data and power connectivity alongside UART interface and external trigger inputs, facilitating easy integration into drones, robotics, industrial automation, and other applications requiring compact, accurate depth sensing. With a horizontal field of view (HFoV) of 30° or more and a measurement accuracy of ±0.2 inches at 10 meters, the AS-DT1 combines precision, speed, and miniaturization for advanced 3D sensing needs.
