Stereogram implemented with a holographic image splitter
Optics Express, 2011 A special holographic optical element (HOE) which is used as an image splitter is developed to generate a stereogram on a 2.2-in. liquid crystal display panel. The special designed holographic optical element can be attached on the conventional panel directly to replace the traditional image splitter in a stereoscopic display panel.

Interactive holographic stereograms with accommodation cues [PDF]
SPIE Proceedings, 2009 Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that (like other stereograms) they do not present accommodation cues consistent with vergence cues and thus

Real-time shader rendering of holographic stereograms [PDF]
SPIE Proceedings, 2008 Horizontal-parallax-only holographic stereograms of nearly SDTV resolution (336 pixels by 440 lines by 96 views) of textured and normal-mapped models (500 polygons) are rendered at interactive rates (10 frames/second) on a single dual-head commodity graphics processor for use on MIT’s third-generation electro-holographic display. The holographic fringe

Generating Multi-Depth 3D Holograms Using a Fully Convolutional Neural Network. [PDF]
Adv Sci (Weinh)This work introduces the forward–backward‐diffraction framework for computing multi‐depth diffraction fields and the layer‐by‐layer replacement method for handling occlusion relationships. When combined with a fully convolutional neural network, it generates multi‐depth holograms with excellent depth focusing and corrects occlusion relationships.

Near‐Field Measurements of Water‐Entry Sound of Low‐Speed Metal Balls in a Non‐Anechoic Tank
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 As one of the target characteristics, water‐entry sound characteristics are of great significance to study, and its research has certain reference value for the detection of sea target. The water‐entry sound of an underwater target is a transient sound signal, and it is mainly measured in open water such as the sea and lakes.
