Paper Abstract

An interferometer system scheme is proposed. This system consists of two Michelson interferometers and two laser sources and requires no use of modulation technique. Within a displacement range of about 10 microns, it is expected that the absolute displacement can be measured with a very high speed without the phase ambiguity problem. The possibility is demonstrated by numerical analysis.
