Abstract
A holographic system for phasing of multimodule synthesized aperture optical telescope is proposed. A phasing test system model is theoretically analyzed for an implementation being composed of three flat transmissive diffraction gratings with identically oriented and equidistant lines of diffraction hologram structures. The proposed holographic system irradiation by an infinitely far nonmonochromatic source is shown to result in the telescope focal plane as a noncoherent addition of monochromatic fringe pattern of the same phase and orientation produced by the beams having passed through the telescope modules. A criterion for phasing accuracy estimation is proposed being ratio of fringe pattern phase increment measured in any point of the telescope focal plane to the irradiation wave length change which has caused this increment. Mathematical expression is obtained describing the dependence of the achieved phasing accuracy on tolerance values for the modules geometrical parameters.
