Optical sensors
from Sicatron

Optoelectronic sensors have the task of converting optical information into electrically evaluable signals. This is mainly limited to visible light, as well as infrared radiation and ultraviolet light. The basis of optical sensors is the conversion of signals by quantum mechanical effects of light.

Photocells, for example, use the external photoelectric effect. Optical sensors can also be based on the internal photoelectric effect, in which case they consist of semiconductors in which the action of light creates charge carriers that change the electrical properties of the material. The incident light therefore causes either a change in electrical conductivity (photoresistance) or a photovoltage (photodiode or photoelement). A variant of the internal photoelectric effect is the junction photoelectric effect, it is used in phototransistors and also photodiodes. Optical sensors in digital photo and video cameras (CMOS and CCD sensors) and in pattern recognition (e.g. barcode scanners) are often referred to as image sensors.

Optical sensors are used primarily in automation technology. There, in addition to simple recognition tasks, they are used for position measurement (e.g. light barrier), speed and angle measurement (e.g. incremental encoder) and distance measurement.

Optical sensors are at the heart of advanced manufacturing automation. Their reliability determines the function of the entire system. The properties have a decisive influence on your costs, economic efficiency and quality. Pepperl-Fuchs offers one of the largest ranges of modern optoelectronic sensors with the VISOLUX brand.
