Abstract

Here, we consider one of the most important problems related to optimizing the performance data of a new acoustooptical spectrometer for the analysis of radio-astronomical signals. The main attention is paid to estimating two factors governing the dynamic range of that spectrometer. At first, we determine the influence of the acoustic attenuation along a large-aperture acousto-optical cell on potential levels of lobes in focal plane of the integrating lens and then describe capabilities of the incident light beam apodization for increasing the dynamic range of spectrometer. These studies lie in a line with the program of developing metrological equipment for Mexican Large Millimeter Telescope.
