ABSTRACT:
Apparatus for measuring displacement between two bodies one of which is provided with a light reflecting target area having a sharply delineated boundary. The other body has two fiber optic bundles one of which has a light emitting end adjacent the boundary of the light reflecting target area. The other bundle has a light receiving end adjacent the light reflecting area adapted to receive light reflected from the area. The arrangement permits use of the transducer in a hazardous or inconveniently accessible area with an output which may be located remote from the body.
