Abstract:

The monitoring of the assembly and alignment (positioning) of the elements of segmented mirrors of telescopes is proposed using the axial synthesized holograms and coherent properties of laser radiation sources. By examining the segmented primary mirror of the Millimetron telescope, whose carbon-fiber-reinforced composite panels form four ring-shaped tiers, the possibility of detecting the deviations of each of the 24 identical panels of the same tier from the set positions and the sign and magnitude of the errors of the interposition of panels of the neighboring tiers near the places of their “dockings” are considered.
