FIELD: optics.
SUBSTANCE: optical projection system on-board indicator comprises spherical beam-splitting mirror (combiner). System also includes secondary mirror, made in form of wedge and with spherical reflecting and refracting surfaces, lens projection optical system made of three components. Before first component of lens projection optical system there is polarisation plane-parallel plate, and third component comprises positive hyperbolic meniscus optical lens, which is installed between display and elliptical meniscus lens with equivalent optical power φ3 of component. Second component is displaced with optical axis and inclined clockwise around first surface.
EFFECT: technical result consists in increase of exit pupil and elimination of solar flares.
