For other uses, see Electric eye (disambiguation).

An electric eye is a photodetector used for detecting obstruction of a light beam. An example is the door safety system used on garage door openers that use a light transmitter and receiver at the bottom of the door to prevent closing if there is any obstruction in the way that breaks the light beam. The device does not provide an image; only presence of light is detectable. Visible light may be used, but infrared radiation conceals the operation of the device and typically is used in modern systems. Originally systems used lamps powered by direct current or the power line alternating current frequency, but modern photodetector systems use an infrared light-emitting diode modulated at a few kilohertz, which allows the detector to reject stray light and improves the range, sensitivity and security of the device.

Examples

Highway vehicle counter

• In the 1930s an electric eye vehicle counter was introduced in the US using two IR lamps set apart so that only cars and not pedestrians would be counted.

First compact commercial unit

• Also, a compact type of electric eye was offered in 1931 that was enclosed in a small steel case and much easier to install compared to older models.

Automatic wrapping machines

• In the 1930s an electric eye apparatus was developed to help a wrapping machine, wrap 82 boxes a minute.

Automatic door opener

• In 1931 General Electric tested the first automatic door openers now popular in hospitals. They called their electric eye, the Magic Eye.

Business alarm system

• In 1931 an electric eye that used invisible UV wavelength was offered to businesses in need of a 24-hour alarm system. A system of this type is demonstrated in the first scene of the 1932 film Jewel Robbery.
