摘要: An Optical Projecting Encoder (“OPE”) having an emitter module for transmitting emitted optical radiation through a mask to moving object, and detector receiving reflected from the object. The object may include predetermined image cast by surface texture OPE transmissive layer covering both module, where collimates concentrates module. navigation sensor that continuously acquires compares images
