Abstract: There is provided a layered combiner for manipulating optical polarization on toroid surfaces, e.g. for a head-up display applications comprising a Picture Generating Unit (“PGU”) the structure adapted to receive polarized light in p-polarization direction, from said PGU, said structure comprising a dielectric material further comprising: a first layer comprising a first wave-retarder, wherein the angle between the incidence angle and the optical axis of the wave-retarder satisfies a Brewster angle; a layer of PMLTC segments, wherein each of the segments acts as a Mangin mirror-type surface and a third layer comprising a second wave-retarder. The Mangin mirror-type surface is configured to modulate the reflection of incoming collimated light on the surface of the segment to provide a collimated wave front without toroidal aberration thereby providing an observer with an undistorted image.

Abstract: A Dynamic Parallel Monocular Projection (DPMP) system for the provision of dynamically adjusted images to a Head Motion Box (HMB) is provided herein. The DPMP may include a picture generation unit (PGU); a projection unit, further comprising a displaying unit and at least one optical modulator, a Multi-Layered Thin Combiner (MLTC), comprising an infra-red (IR) light source and an IR detection sensor, thereby enabling the provision of images adjusted to the individual location of the observer's eyes within the HMB.
