Reflective Optical Sensors – Optical Sensor Types

An optical sensor changes light rays into electronic signals. It measures the physical quantity of light and then translates it into a form that is readable by an instrument and or device. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device and instrument and the optical sensor. This is often connected to an electrical trigger. The trigger reacts to a change or alteration in the signal within the light sensor. An optical sensor will measure the changes from one or several light source beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output.

An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively from one circuit to the next circuit. An optical switch can operate by mechanical means or by electro optic effects, magneto optic effects as well as by other methods. Optical switches are optoelectronic devices which can be integrated with integrated or discrete micro electronic circuits.
