Abstract: Systems and methods for shear-corrected digital hologram acquisition, wherein the shear-corrected geometry is highly suited for two (or more) color operation with either broadband or laser illumination. An apparatus for shear-corrected recording of a spatially heterodyne hologram with broad-band or laser illumination includes: an illumination source; a beamsplitter optically coupled to said illumination source(s); a reference beam corner-mirror pair for translation and phase-shaping of the object beam optically coupled to the beamsplitter; an object optically coupled to the beamsplitter; a focusing lens optically coupled to both the reference beam corner-mirror pair and the object; and a digital recorder optically coupled to the focusing lens. A reference beam is incident upon the translating and phase-shaping corner-mirror pair, and the reference beam and an object beam are focused by the focusing lens at a focal plane of the digital recorder to form a spatially heterodyne hologram.

Abstract: Systems and methods for shearless digital hologram acquisition, including an apparatus incorporating an illumination source configured to produce a first beam of light, which is then split by a beamsplitter into a reference beam and an object illumination beam. The reference beam is directed onto a phase-shaping optical element which imparts a phase shift to the reference beam and returns the phase-shifted reference beam on itself to the beamsplitter. The object illumination beam is directed onto an object, and a portion of the beam is reflected back to the beamsplitter, which combines the phase-shifted reference beam and object illumination beam substantially coaxially. The combined beams are passed through a focusing lens which focuses them at a focal plane. A digital recorder is positioned at the focal plane to record the spatially heterodyne hologram formed by the focused phase-shifted reference beam and reflected object illumination beam.

Abstract: Systems and methods for generating a true 3-D display, where each of a viewer's eyes not only sees a different scene, but the scene changes continuously as the viewer moves his/her head or change his/her position from one angular location to another angular location with respect to the display screen. In one embodiment, a system comprises a set of 2-D image projectors and a display screen. The 2-D image projectors are configured to project individual 2-D images substantially in focus on the display screen. The display screen then diffuses (or reflects) each pixel from each of the 2-D images into a small angular slice. This enables the viewer observing the display screen to see a different one of the 2-D images with each eye. Further, the image seen by each eye varies as the viewer moves his or her head with respect to the display screen.
