FIELD: physics, optics. ^ SUBSTANCE: invention relates to the field of special-purpose optical instrument engineering, in particular, to visualisation systems, simulators using helmet-mounted displays, virtual reality systems, etc. The helmet consists of two identical channels. Each channel consists of a beam splitter and a spherical mirror installed in series, as well as of a positive lens, the second beam splitter, a parabolic mirror, and a liquid-crystal display. A video camera, a video image correction unit, and a virtual image generation unit are used. The spherical mirror is located at a curvature radius distance from the crystalline lens of the eye. The positive lens is installed at the same distance from the spherical mirror. The parabolic mirror is installed after the second beam splitter, at a distance equal to its focal distance from the positive lens. The liquid crystal display is installed at the focal distance from the parabolic mirror. The video camera is installed at the optical axis, after the second beam splitter, and is connected with the video image correction unit. The technical effect is the development of an optoelectronical helmet-mounted system that allows to match the virtual and real spaces automatically and accurately regardless of the mutual position of the operator head and the helmet, and to introduce compensation for the mutual drift of the optical helmet components. ^ EFFECT: development of optoelectronical helmet-mounted system that allows to match virtual and real spaces automatically and accurately, possibility to introduce compensation for mutual drift of optical helmet components. ^ 2 cl, 4 dwg |
