“…In this display a multi-view holographic stereogram is produced in what is termed a diffraction specific coherent (DSC) panoramagram [81]. This provides a sufficiently large number of discrete views to provide the impression of smooth motion parallax.…”

This chapter covers the state of the art in stereoscopic and autostereoscopic displays. The coverage is not exhaustive but is intended that in the relatively limited space available a reasonably comprehensive snapshot of the current state of the art can be provided. In order to give a background to this, a brief introduction to stereoscopic perception and a short history of stereoscopic displays is given. Holography is not covered in detail here as it is really a separate area of study and also is not likely to be the basis of a commercially viable display within the near future.Keywords Autostereoscopic display Á Binocular parallax Á Crosstalk Á Depth cue Á Disparity Á Geometrical distortion Á Glasses Á Head-tracked display Á Image artifact Á Integral imaging Á Light field display Á Monocular cue Á Multi-view display Stereoscopic display Á Stereoscopic perception Á Viewing zone Á Volumetric display Stereoscopic PerceptionThere are many factors involved in stereoscopic perception, and the relative importance of contributory perceptual factors in natural vision is not necessarily the same as for an artificial image. Consider a natural scene being observed; when one eye is covered the image appears to lose very little realism. However, images reproduced on a display appear to be considerably more realistic when stereo is applied to the image. This is particularly well demonstrated if an image is viewed

“…Using consumer-grade range cameras (such as the Primesense structured-light 3-D scanner contained in Microsoft's Kinect peripheral), we have previously demonstrated the utility of the DSC Panoramagram approach in rendering holographic images of real scenes at real-time rates. 6 Figure 3 depicts the high-level pipeline used for scene capture via a single Kinect camera and holographic fringe pattern computation via the DSC Panoramagram approach.…”

A holographic television system, featuring realtime incoherent 3D capture and live holographic display is used for experiments in depth perception. Holographic television has the potential to provide more complete visual representations, including latency-free motion parallax and more natural affordances for accommodation. Although this technology has potential to improve realism in many display applications, we investigate benefits in uses where direct vision of a workspace is not possible. Applications of this nature include work with hazardous materials, teleoperation over distance, and laparoscopic surgery. In this study, subjects perform manual 3D object manipulation tasks where they can only see the workspace through holographic closed-circuit television. This study is designed to compare performance at manual tasks using holographic television compared to performance with displays that mimic 2D, and stereoscopic television.

Applications of digital and analog holography in three-dimensional imaging

Doc. ID 166543)Digital and analog holography, along with its many variations, viz., holographic interferometry, holographic microscopy, holographic tomography, multiwavelength digital holography, phase-shifting holography, compressive holography, coherence holography, etc., have become the methods of choice for various metrological applications in three-dimensional (3D) imaging. In this review, we discuss the basic principles of analog and digital holography and the various topics mentioned above, with selected applications to real-world problems. We also discuss other related topics such as dynamic holography, non-Bragg orders, and compressive holographic tomography, nonlinear holography, holographic TV, as well as a nonholographic technique for 3D visualization, viz., transport of intensity imaging. Finally, we expose interested readers to contemporary topics in the area, viz., nonlinear holography and real-time holographic TV.
