Title: Optical wavelength measuring apparatus
Inventor: SONOBE YOJI
IPC: G01J9/00
Filed: 1988-07-05
Abstract: PURPOSE:To implement high accuracy in measurement of optical frequency to be measured over a wide frequency range by using sweeping light whose frequency is continuously changed and an etalon. CONSTITUTION:When the wavelength of incident light is continuously changed in an etalon 1, a light intensity signal (j) which is outputted from a sweeping light receiver 10 generates a plurality of peak signals 2. The sweeping signal (g) whose frequency is continuously changed and light to be measured (e) 1 whose frequency is unknown are inputted into a light combiner 5. The beam frequency DELTAf of the combined light (h) is located within an analyzable frequency range of a frequency analyzer 8 during the sweeping of the light (g) without fail. A reference frequency (c) of a reference frequency f1 is the same. In this way, a measuring reference frequency Fsa of a measuring reference peak signal of the light (g) at the time point 2a when the beat frequency corresponding to the light (c) (or light (e)) is measured in the analyzer 8 (or a peak signal frequency Fsb at a time point 2b) is determined (or specified). Therefore, the frequency difference between the signal 2 and the measuring reference peak signal is obtained by multiplying the number of the signals 2 in the region by a frequency interval DELTAF. Finally, the frequency of the light (e) can be computed by the specified expresion.
