Abstract

A digital angle measurement technique based on Michelson interferometer is introduced in the paper.Through changing the angular displacement into linear displacement,using special circuits to subdivide and measure the interference pattern,exact measurement for a big angle is realized.Compared with other similar measuring system,this system can be applied to wider-angle measurement with high accuracy.The principle of the system,some special notes and error analysis have been introduced.
