Title: Determination and automatic control of optical thickness of scanning Fabry-Perot interferometer

Abstract

This paper presents a method and a device for determination and control of the optical thickness of a scanning Fabry-Perot interferometer (FPI) of 973 to 29,800 um with a relative error of o.04%. The device scans the optical thickness of the interferometer itself and records the shift of the interference peaks when the interferometer is exposed to radiation containing two wavelengths. The interferometer is exposed to the collimated radiation of a VSB-2 spectroscopic lamp filled with mercury isotopes Hg 198 and Hg 204. A ZS-1 glass filter separates the two wavelengths and the transmitted light at the output of the FPI has an interference pattern formed by two independent systems of rings. It is noted that the disadvantage of the described device is the complexity of preparing interferometer-plate reflecting layers that have high reflection coefficients for the two working wavelengths simultaneously.
