MULTICHANNEL DYNAMIC IR FOURIER-SPECTROMETER
Abstract
A scheme of the multi-channel continuous scan Fourier spectrometer is proposed for simultaneous recording and analysis of the spectral characteristics of several objects. The scheme is realized using a multi-probe fiber in which several optical fibers are connected in one optical connector and fixed in the output of an interferometer. The Fourier spectrometer is used as a sygnal modulator. Еach fiber is individually mated with the studied sample and its own radiation detector. For the developed system, the spectrometer aperture is calculated from the condition of the minimum spectral resolution and parameters of the optical fibers. With the help of the proposed scheme, the emission spectra of a gas-discharge neon lamp have been recorded using a single fiber with a diameter of 1 mm and a numerical aperture NA = 0.22.
