Abstract
In addition to laboratory program of Fourier spectroscopy a computer training program 'Fourier-transform visible spectrometer' has been developed. The program main menu contains items: 'Theoretical part', 'Practical part' and 'Exit'. In the first part such topics as 'Michelson interferometer', 'Fourier spectroscopy advantages', 'Fringe pattern scanning and recording', 'Spectrum with interferogram connection' are discussed. Selecting one of these items students can see textbook pages with schemes and illustrations. Some pictures are animated. 'Practical part' includes modeling of radiation spectra and interferograms. Students can simulate spectrum as a sum of gaussian functions with arbitrary center position and width or as sum of monochromatic lines. Then interferogram with given full path difference and scanning step is calculated and corresponding spectrum is reconstructed. Comparing this spectrum with initial one students investigate the influence of scanning range and step on spectrometer resolution and available spectral range. There is also an opportunity to simulate some device imperfections: not exactly parallel mirrors, occasional mistakes of scanning step, noises, discretion and nonlinear respond of photo detector. The program has Russian and English versions. It is used as a part of laboratory training of physics and instead of lectures on Fourier spectroscopy for the Physics Electronic Department students. For advanced students we have also the program, which simulates Fourier-colorimeter.
