Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. These sensors are able to detect electromagnetic radiation from the infrared up to the ultraviolet wavelengths.[1] They are used in many industrial and consumer applications, for example:
- Lamps that turn on automatically in response to darkness
- Position sensors that activate when an object interrupts a light beam
- Flash detection, to synchronize one photographic flash to another
- Photoelectric sensors that detect the distance, absence, or presence of an object
