A Fourier-Transform Spectrometer for Operation on Mars

Аннотация

The design, principle of operation, and results of tests of a Fourier-transform spectrometer, which is designed for studying the composition of the Martian atmosphere by the transmission technique, are described. A standard specimen of the instrument must operate on the landing platform after its delivery to Mars. The spectral range of the manufactured specimen is 0.5–4 μm, the spectral resolution is 0.04 cm^–1, the aperture is 25 mm, and the mass is 1.1 kg.
