Abstract
Development of a parametric model of an optical system consisting of 2 and 3 reflective surfaces and its analysis are considered in this paper. The construction of a parametric model is necessary to simplify the initial stage of designing optical systems. The basis of the parametric model is built by replacing reflective surfaces on thin components equivalent, in which a three-mirror system can be written using an external virtual axis angles (zero) beam with the optical axis. To solve the problem of minimizing aberrations, the theory of third-order aberrations developed by Professor G.G.Slyusarev is used. As a result of working is a universal equation, describing the entire variety of optical systems of three thin mirror components forming a flat image, the design parameters of which depend on the 3 coefficients that enter the equation. The use of the obtained parametric model of an optical system consisting of 3 reflecting surfaces makes it possible to simplify the stage of the initial synthesis of mirror optical systems and to obtain an initial version of a system free from spherical aberration, coma, astigmatism and curvature of the image.
