ABSTRACT:
A fiber optic encoding device capable of long term reliable operation in hostile environments is disclosed. Various construction details which contribute to a compact device with high mechanical reliability are discussed. An encoder formed to a cylindrical geometry including a correspondingly shaped code plate is shown in detail. The code plate has a multiplicity of apertures arranged in rows to produce an encoded position signal of the type suitable for use in digital intelligence processing equipment.
