Issues Practical Implementation of the Receiving System Infrared Space Telescopes and Testing it at Low Temperatures

Abstract:

To clarify the physical basis for creating an infrared telescope, an equation was obtained that describes the dispersion of the error in measuring the input flux against the background noise. For the first time, a three-beam spatial modulation method has been developed, which provides increased accuracy of infrared observations during astrophysical studies of space objects and a precision scanning device with compensation for inertia force, and it was found that when testing a scanning device made of Al-Cu-Mg D16T1 alloy, the cooling process of the stationary part of the device occurs slowly than the scanning part with an average temperature difference about 20°.
