HELMET-MOUNTED WIDE-ANGLE COLLIMATING OPTICAL DISPLAY SYSTEM Russian patent published in 2016 - IPC G02B27/01 G02B27/30 G02B13/18 

FIELD: optics.

SUBSTANCE: helmet-mounted wide-angle collimating optical system comprises display projector, including liquid crystal display, lens projection system consisting of three components, two-mirror component and splitting collimating concave mirror, connecting image from outer space and from liquid crystal display. Projection lens system made with telecentric stroke of main beams in space of liquid crystal display. At that, first component comprises biconvex lens and positive meniscus, second component is made of positive and negative meniscus and negative hyperbolic biconcave lens. Third component is made from positive meniscus and biconvex lens.

EFFECT: technical result consists in simplifying design of protective glass helmet-mounted system, providing telecentric main beams in space of liquid crystal display, increase brightness due to illuminate liquid crystal display reflected polarised beams, normal to display surface, and provision of high quality on entire field of entrance to pupil diameter of not less than 14 mm.
