Fiber-optic sensor - Wikipedia

A fiber-optic sensor is a sensor that uses optical fiber either as the sensing element ("intrinsic sensors"), or as a means of relaying signals from a remote sensor to the electronics that process the signals ("extrinsic sensors"). Fibers have many uses in remote sensing. Depending on the application, fiber may be used because of its small size, or because no electrical power is needed at the ...

Optischer Näherungsschalter – Wikipedia

Optoelektronische Sensoren haben allgemein eine große Reichweite. Besonders empfindlich reagieren optische Sensoren auf Nebel oder Partikel in der Luft, da der Lichtstrahl dadurch stark gedämpft oder unterbrochen werden kann. Verschmutzungen im Bereich der Optik führt meist zur Fehlfunktion oder zum Ausfall der optischen Sensoren

Different Types of Optical Sensors and Applications

For optical sensors to work effectively, they must be the correct type for the application, so that they maintain their sensitivity to the property they measure. Optical sensors are integral parts of many common devices, including computers, copy machines (xerox) and light fixtures that turn on automatically in the dark. And some of the common applications include alarm systems, synchros for ...
