Abstract
An optical shutter encoder provides a mechanism for monitoring a state condition of an apparatus. A shutter assembly is adapted to have an aperture that varies with the changing state of the apparatus feature being monitored. An optical emitter and detector are provided to sample the condition of the shutter, that is, to determine if it is open, partially closed, or fully closed. The shutter condition is indicative of the state condition. A series of encoders is provided to monitor repetitive devices of the apparatus; the emitter and detector pair are moved to sequentially sample each shutter, thus providing the state condition of each repetitive device of the apparatus.
