TOF is short for Time of Flight. The technology is widely used for the following three categories, human face recognition, sweeper obstacle avoidance, and autofocus.

TOF camera is composed of light, optical components, sensor, control circuit, and a processing circuit.

What Does TOF Mean in Projector

If your projector adopts TOF technology, it can relieve you from the trouble of manual focus. That’s to say, a projector adopting the TOF sensor can adjust the focus automatically and quickly based on different distances and different image sizes.

What Does TOF Mean in Projector

For some projectors without an autofocus feature, you need to move the projector repeatedly to make the image clear if you want to change the image size or position.

What Does TOF Mean in Projector

TOF technology can detect the projection distance and then adjust the optical path to make the image clear. The sensor will emit optical pulse (invisible light) onto the Observed object (wall or screen) and receive the reflected light, then calculate the distance by means of the flight time of the optical pulse. It is worthy to note that the technology has distance limits of no more than 3 meters.

In short, TOF technology brings your projector with an autofocus feature, making your image adjustment easier.
