Paper Abstract

We report here a method to measure the cavity spacing of a Fabry-Perot interferometers with error less than several tenth of wavelength. First the central fractional order was obtained from the interference pattern by a OMA system, which consists of diode array and microcomputer, for 32 different wavelength and He-Ne 6328 line . Than by using the method of excess fractions to process data the absolute interference order and the cavity spacing of Fabry-Perot was worked out from data corresponding to at least to 4 different wave-length. Further more , the relative reflection phase dispersion curve for silver Mirror was also obtained by the fitting data method.
