An optical sensor converts 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. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device and the optical sensor. This is often connected to an electrical trigger. The trigger reacts to a change in the signal within the light sensor. An optical sensor can measure the changes from one or sever… Web– A pick-off sensor for a reference pulse is also used. • Signal interpretationdepends on whether the particular optical encoder is an incremental device or an absolute device. – We will focus on the incremental optical encoder. – The output signals from either the offset sensor configuration or the offset track configuration are the same.
