Abstract
A position detector for use with a code carrier which defines a position and has alternating radiation transmissive and non-transmissive regions which define a multi-bit output is disclosed. The position detector includes a photodetector array mounted on one side of the code carrier and a radiation source mounted on the detector on the side opposite the photodetector array. A radiation guide is interposed between the code carrier and the photodetector array and has a plurality of radiation transmissive paths each of which is in exclusive communication with one photodetector.
