Abstract
An improved optical transducer includes optical transmitter and receiver heads and an encoder plate movable therebetween on channel-shaped tracks integral in part with an inner housing. The encoder plate, and optical heads are disposed in an optical fluid which minimizes light refraction between those optical components, cushions against shock and vibratory loading, and lubricates the encoder plate tracks. The transducer includes an input shaft connected to the encoder plate by means of a coupling which isolates the encoder plate from misalignments of the input shaft and eliminates free-play in the connection between the encoder plate and input shaft, thereby eliminating backlash in the reciprocation of the encoder plate for improved transducer accuracy.
