WIDE-ANGLE VIRTUAL HELMET WITH POSSIBILITY OF COMBINATION OF REAL AND VIRTUAL SPACE Russian patent published in 2007 - IPC G02B27/22 

FIELD: the invention refers to optics and is designed for creation a three-dimensional image combined with real ambient space with the aid of the virtual helmet.

SUBSTANCE: the helmet has two channels and a system of coordination of the helmet in the space. In each channel there is a half-transmitting dividing mirror, a positive mirror-like Frenel's lenses, a liquid-crystal information screen. The dividing mirror is optically connected with the mirror-like Frenel's lenses and the eye of an observer. The liquid-crystal screen is located on a focus distance from the mirror-like Frenel's lenses. The lighting of the liquid-crystal information screen is executed with a block of light diodes with Frenel's lenses . In each channel may be additionally used the second half-transmitting flat dividing mirror and two positive mirror-like Frenel's lenses. In each channel half-transmitting flat dividing mirrors, a spherical mirror, a parabolic mirror are additionally used.

EFFECT: creation of simple in manufacturing virtual helmet with wide-angle survey of virtual image, with possibility of observing the virtual image in a near and a distant zones, combination of real image with virtual.
