An optical system includes an image projector having a light source. A reflective polarizer receives light emitted by the light source at a first incident angle greater than 30 degrees and reflects a portion of the light as a first reflected light. A spatial light modulator receives the first reflected light at a second incident angle greater than 5 degrees and transmits a portion of the first reflected light as a projected image light. A first mirror receives the projected image light at a third incident angle and reflects a portion of the projected image light as a second reflected image light which is received by a second mirror at a fourth incident angle, reflecting a portion of the second reflected image light as a third reflected image light having the viewable image. The light source and spatial light modulator are disposed on a same side of the reflective polarizer.
