ABSTRACT:
Apparatus for determining the displacement or position of an object comprises a light source and a light receiver for receiving light transmitted from said light source, and a fiber optic conduit of Y-shaped configuration having the end of one arm thereof positioned adjacent said light source and the end of the other arm positioned adjacent said light receiver, said conduit arms forming a common bundle of optically conducting fibers in the base of said Y, some of which are transmitting fibers for conducting light from said light source to a surface of the object and some of which are receiving fibers for conducting light reflected from the surface of said object to said light receiver so that the conduit is normally objective to conduct light from said light source and to conduct reflective light impinging on an end face of said common bundle to said light receiver.
