Abstract
An influence is considered that profile shape of a relief hologram structure applied upon a primary mirror surface exerts on power and aberration features of a telescope's information and control channels. Expressions are obtained that give possibility to determine the hologram structure relief height being optimal for various symmetric and non-symmetric shapes of the relief profile and to estimate power loss in the information channel caused by this. As a result of these expressions analysis, it is found that from the standpoint of power loss minimization in the information channel the relief profile of symmetric shape is optimal being near-to- sinusoidal shape or near-to-triangular one with porosity of 0.5. Expressions are given, too, describing height and shape influence of the hologram structure profile and variations of these within the primary mirror aperture on aberrations in both information and control channels of a telescope. Basic requirements are formulated that are made for profile shape of the hologram structure applied upon the telescope primary mirror.
