Abstract:
An optical encoding arrangement for determining the position of a movable member is provided with an optically masked light transmitting coding element interposed between a light emitting array and a light detecting array so that the light detecting elements in the array are selectively energized in accordance with the position being measured. In particular, the encoder provides for transmission, by optical means, of a series of digital bytes of predetermined length, in a bit parallel byte serial format, with the successive bytes later being assembled into a usable data format.
