Patent number: 11415812Abstract: 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.Type: GrantFiled: June 24, 2019Date of Patent: August 16, 2022Assignee: LUMUS LTD.Inventor: Mali Mansharof
