Grove - TF Mini LiDAR
This product is based on ToF (Time of Flight) principle and integrated with unique optical and
electrical designs, so as to achieve stable, precise, high sensitivity and high-speed distance
detection.
ToF is the abbreviation of Time of Flight technology, and its operating principle is as follows: a
modulated near-infrared light is sent from the sensor and reflected by an object; the distance to
the object to be shot can be converted with the sensor by calculating the time difference or
phase difference between the light sending and the light reflection, so as to produce the depth
information.
