Wide-angle head-up display with three-component combiner

摘要

HUD wherein increasing of full and instantaneous angular fields of view horizontal and vertical is achieved by using two or several unified sources of collimated image USCI arranged in horizontal plane, containing main and secondary optoelectronic channels each consisting of a display module forming a part of full primary image and axisymmetric collimating lens system with square shaped angular field of view provided with single optical combiner for viewing combined collimated image of primary information picture against outer space background consisting of three semitransparent reflectors, first and second installed mutually parallel above output lenses of USCI main channels, third reflector installed above output lenses of secondary channels with optical axes located between first and second reflectors and shifted related to first reflector at an angle under which operating beams of secondary channels pass through eyes box of operator.

主权项

1. A wide-angle HUD for forming collimated image of information picture to enlarge full and instantaneous angular fields of view in horizontal and vertical directions comprising:
two or several unified sources of collimated images USCIs spaced in horizontal direction, each USCI having main and secondary optoelectronic channels, each channel having a display element forming specified part of primary information picture, a collimating system, and an output lens; and an optical combiner for viewing combined collimated image of primary information picture formed by all USCIs against outer space background.
