Long-range TOF multi-machine jamming system

TOF (Time of Flight) is a key technology in the field of 3D depth detection. The AFE (analog front-end chip) drives the infrared laser to emit modulated light pulses to the detection target, and then uses the image sensor to receive the light reflected from the object, and calculates the distance between the target and the camera by calculating the round-trip flight time of the light. TOF technology can be divided into CMOS TOF and CCD TOF according to the type of image sensor.
The ADI TOF system uses CCD as the image sensor, and can be matched with light sources of different intensities for applications in different distance modes. In addition, ADI TOF is based on a pulse-based test method, which can make long-distance detection easier.
