Paper Abstract

Graduating rules used as length etalons in optical measuring instruments and tools need to be checked for graduation accuracy. The best way to perform this is by using a laser interferometer as a linear displacement transducer, some specially designed optoelectronic interfaces, and a computer for control and data processing. Implementation of measuring equipment consisting of these assemblies is described below.
