AX4010 is a DTOF(Direct Time-of-Flight) depth image sensor independently designed by ABAX, featuring high precision, high resolution, low power consumption, small pixel size etc. The chip adopts global shutter with a pixel array resolution of 100×80, the actual resolution of which dependents on the resolution of the transmitting end faculae. The chip uses SPAD array for single-photon ranging to ensure a detection distance of at least 5m when the emission average power is greatly reduced to 15mW. A high-precision clock less than 70ps is provided inside the chip to ensure that the ranging accuracy is less than 1cm (or <1% uncertainty).
