This LiDAR depth sensor adopts the “Direct Time of Flight (dToF) method*1,” which delivers highly accurate measurement, distance resolution*2, and measuring range.
By employing the proprietary dToF ranging module equipped with a Single Photon Avalanche Diode (SPAD)*3 sensor, and by utilizing multiple ranging points for distance measurement, it can accurately measure distances in three dimensions: length, width, and depth. Furthermore, it can also measure distances to low-contrast objects, objects with low reflectivity, which are more difficult to detect using other ranging methods.
This enables accurate distance measurement in environments such as retail stores, where various objects, including people and fixtures, are expected. In addition to its ability to accurately measure the distance to objects both indoors and outdoors, the sensor’s compact, lightweight design and robust aluminum housing allows it to be integrated into various devices, such as food serving robots in restaurants, autonomous mobile robots in warehouses, and drones used for inspections and surveys.
*1A ranging method that calculates distance by measuring the time it takes for light to be reflected back from an object.
*2The ability to recognize minute differences in distance between multiple objects.
*3An electronic device (diode) that achieves high sensitivity by utilizing “avalanche multiplication,” which amplifies electrons like a snow avalanche from a single incident photon.
