ABSTRACT:
An optically coupled shaft angle encoder for measuring the relative rotational angle of a shaft includes a mirror mounted on the shaft, a light source for transmitting light to the mirror and a linear array of photosensitive detectors for receiving light reflected by the mirror. The number and relative position of the photosensitive detectors of the array which actually receive reflected light is indicative of the angular position of the shaft.
