Abstract
An optical detector assembly is disclosed for detecting light-dark variations in an encoded surface or the like. The assembly includes a resilient ferrule having a profiled bore for receiving a transmitting and a receiving optical waveguide therein in axially adjacent relationship and crimping means for radially compressing a nose portion of the ferrule around the waveguides holding the waveguides in closest proximity. End surfaces of the assembly waveguides and resilient ferrule are subsequently prepared at a common prescribed angle so that, upon normally positioning the detector assembly above the encoded surface, transmitted light is refracted at the transmitting waveguide end surface toward a relatively small detection zone of the encoded surface. The like-angled end surface of the receiving waveguide receives, with refraction, light reflected from the detection zone.
