ABSTRACT:
A rotary encoder comprises a light emitting device, a photosensor, sampling means arranged between the light emitting device and the photosensor for intercepting the light emitted by the light emitting device as the sampling means is rotated, monitoring means arranged on a side of the sampling means facing the light emitting device in adjacent to the light emitting device for sensing a portion of the light from the light emitting device and producing a signal representing a light intensity sensed, and control means for controlling the light intensity of the light emitting device in accordance with the output of the monitoring means.
