PROJECTION OPTIC SYSTEM WITH DISTORTION COMPENSATION

摘要

FIELD: optic systems. ^ SUBSTANCE: system comprises the projection optic device, screen and distortion compensation device. The projection optic device contains the light source and optic elements. The distortion compensation device contains the elastic plate and means of plate deformation and is positioned between the screen and light source. The device design provides formation of optical beam transferring the image onto screen and optical beam projection onto screen through the plate. The distortion compensation device design provides the compensation of the image distortions in screen angles; the said compensation is provided with unbending of plate angle parts on which the part of light beam is projected. The means of plate deformation provides the possibility of unbending of the plate angle parts and its fixing in deflected state. ^ EFFECT: construction of the projection optic system with distortion compensation; design simplification; overall dimension decreasing, enhancement of the functional capabilities. ^ 8 cl, 4 dwg
