CATADIOPTRIC SYSTEM Russian patent published in 2002 - IPC

FIELD: optical instrumentation, information recording and reading. SUBSTANCE: proposed catadioptric system includes at least one refracting element in which zone of input surface object plane is organized, at least one beam splitting element and at least one reflecting surface which jointly form main optical system that is accomplished with autocollimation path of rays near specified reflecting surface. Refracting element of main optical system is divided into two spaced apart parts, as minimum, along separation surface of specified form. Main optical system is provided with optical component 10 in which central region above- mentioned beam splitting element is positioned and which is installed between specified parts of refracting element with potential for display with unit magnification of surfaces of separation of said parts. In addition catadioptric system is equipped with additional optical system with image plane organized across its output. Additional optical system is identical to main optical system by composition and configuration and is arranged in mirror symmetry to specified part of main optical system relative to division plane of beam splitting element. Aberrations acquired on surface of separation of one part of refracting element are compensated after refraction on surface of another part of refracting element. EFFECT: obtainment of wide flied of vision without deterioration of image quality. 6 cl, 8 dwg
