In this paper, a Michelson form interferometer not only acts as a pure unit of measurement, but also as part of the digital encoder. When a normal beam splitter is taken place of the special one which made of photorefractive material, the orders of the diffraction correspond the path light intensity and its fringe. The out put field is shown as array form. Signal would be sent by optical fiber and all system is full optical with quasi-digitized code.
