Light gates are simple optical circuits that have an opening between an emitter and receiver. If the path between the two is interrupted, a signal is sent to a computer or other data recorder. Some gates work in continuous mode, meaning the signal is different when the light is blocked, for example high or low voltage. Others work in pulsed mode, which responds by giving a pulse whenever the 'state' of on or off changes. And a third kind send a signal continuously while the path is open, and simply stop the signal when the path is broken.
These gates are typically used for timing and detection. Many automatic garage doors use a light gate to detect whether the door will come down on something (or someone!).
