Abstract: An occlusion-capable viewing device includes an imaging lens, a collimating lens, and a virtual display module, and between the imaging lens and the collimating lens, an image inverter, and a spatial light modulator. The imaging lens projects a first inverted image of a scene on to an entrance surface of the image inverter. The image inverter rotates the first inverted image to yield a first upright image. The spatial light modulator attenuates a first image-region of the first upright image to produce a modulated optical beam. The virtual display module includes a display device and a light combiner, which combines (i) the collimated optical beam and (ii) illumination emitted by the display device to yield an occluded image.
