System for Recording Interferograms in a Two-Probe(Two-Channel) Fourier Spectrometer
The optical scheme of a two-probe Fourier spectrometer providing simultaneous measurement of spectral characteristics of two different objects is described. The structural diagram of the control system and registration of interferograms is considered. Main characteristics and parameters of this system are given. The uniqueness and fundamental features of each of the nodes of the system are emphasized. Particular attention is paid to an integrated approach to solving the problem of refining an interferogram signal from a multiplex signal without the use of standard FIFO and LIFO buffers.
