Abstract
The pulsed optical rotary encoder digitally samples the operation of the optical rotary encoder to obtain the same information that is obtained by the use of the continuously active light-emitting devices but in a much more energy-efficient manner. In particular, the light-emitting devices are pulsed into operation for a short duration and at a frequent rate. The signals produced by the light detectors associated with the light-emitting devices are sampled at a predetermined time after firing the light-emitting devices to obtain the data necessary to determine the rotation of the coding disk.
