    Abstract: PURPOSE: A device for measuring wavelength of ray using fabry-perot interferometer is provide to measure the wavelength of ray through a simple structure not including separate frequency-stablized laser or components moving mechanically to equal accuracy level to existing commercial products. CONSTITUTION: A device for measuring wavelength of ray using fabry-perot interferometer comprises a laser(110), an optoelectronic modulator(120), a wave source(121), a beam-splitter, a 1/4 wavelength plate(131), an acousto-optic modulator(132), a frequency changeable wave source(133), a distributor, a demodulator(171), a circuit(172), a light detector(180), a demodulator(181), a circuit(182), a distributor(190), and a frequency detector. The light detector detects rays penetrated through a fabry-perot interferometer. The demodulator demodulates the output signal of the light tdetector to a micro wave source(141).
