A two-dimensional holographic image projection display method. The method includes illuminating a first modulating part of a spatial light modulator with a first incident light beam at a first incident angle with respect to a direction normal to a main surface of the spatial light modulator to form a first projection region on an imaging plane; and illuminating a second modulating part of the spatial light modulator with a second incident light beam at a second incident angle with respect to the direction normal to the main surface of the spatial light modulator to form a second projection region on the imaging plane. The first projection region abuts or partially overlaps with the second projection region at an interface substantially parallel to a lateral direction of the spatial light modulator.

A stereoscopic endoscope that includes at least one image sensor, one or more processing devices, and a display device. The image sensors sense a pair of stereo images, based on capturing light passing through apertures electronically defined at a first aperture location and a second aperture location, respectively, on a liquid crystal layer within the endoscope. The size of each aperture, spacing between the apertures, and polarization state associated with each aperture are controlled using corresponding control signals provided to the liquid crystal layer. The image data captured through the apertures is used to generate control signals representing one or more views of a surgical scene. The views are then presented on a display device.
