Abstract
Optical rotation counter associated with a rotary disc of an angle sensor provided with means for coding the angular position of the disc, including at least one fixed source of coherent light emitting a light beam, a diaphragm and a support moved by the rotation of the coding disc. On its face facing the incident beam, the support includes at least one cell for coding its displacement orientated in the direction of the said displacement and generates an optical code by interference with the incident light beam, the said optical code being readable after interference on at least one photodetector.
