What is Time of Flight (TOF) Technology

Time of Flight technology is the measurement of absolute distance. The sensor produced out the infrared light. The light emitted encounters the object, reflects and then returns to the sensor. The sensor then detects the time difference the light took to reach back and measure the distance of the object and the sensor. Because of having advance features of TOF the technology empowers the sensor to calculate the depth as well. TOF technology has great benefits over the 3D structural light plan and binocular plan.
