An optical system includes an arrangement of optical components including a first polarization-selective reflector (PSR) associated with a third surface of a first prism. The first prism includes an entrance surface having a normal corresponding to a first rectangular axis of the first PSR. The first prism includes a second surface perpendicular to the entrance surface, and has a normal corresponding to a second rectangular axis of the first PSR. The arrangement of optical components defines a light path propagating toward the first PSR, traversing the first PSR, then traversing in a first direction a second PSR, and then reflecting from a second direction from the second PSR in an output image direction. The second PSR is inclined with respect to the first PSR so the output image direction is oblique to the first and second rectangular axes of the first PSR.

Compact collimating optical device and system

There is provided a light-guide, compact collimating optical device, including a light-guide having a light-waves entrance surface, a light-waves exit surface and a plurality of external surfaces, a light-waves reflecting surface carried by the light-guide at one of the external surfaces, two retardation plates carried by light-guides on a portion of the external surfaces, a light-waves polarizing beamsplitter disposed at an angle to one of the light-waves entrance or exit surfaces, and a light-waves collimating component covering a portion of one of the retardation plates. A system including the optical device and a substrate, is also provided.

Collimating optical device and system

An optical device, includes a light-transmitting substrate having an input aperture and first and second major surfaces parallel to each other and edges, one partially reflecting surface located in the substrate which is non-parallel to the major surfaces of the substrate and an external optical arrangement having an output aperture optically attached to the input aperture of the substrate with the part of the substrate located next to the substrate input aperture, being substantially transparent.
