METHOD FOR MODULATING OPTICAL TRAVEL DIFFERENCE IN MICHELSON INTERFEROMETER FOR FOURIER SPECTROMETRY AND FOURIER SPECTROMETER FOR INFRARED, VISIBLE, AND ULTRAVIOLET SPECTRAL RANGES Russian patent published in 2004 - IPC

Abstract RU 2239801 C2

FIELD: spectrometry.

SUBSTANCE: proposed method for modulating optical travel difference in Michelson interferometer for Fourier spectrometry boils down to variation of movable mirror position obeying harmonic law. Proposed Fourier spectrometer for infrared, visible, and ultraviolet spectral ranges has light source, Michelson interferometer with optical travel difference modulator designed for obeying harmonic law in displacement of movable mirror, photodetector, as well as control and processing device.

EFFECT: enhanced precision of movable mirror displacement to obtain high-quality data on investigated radiation.
