Off-axis transmission holographic system for recording aquatic particles [PDF]
, 1996 We describe a holographic system for recording particles suspended in water. The hologram plate is located in air, separated from the test tank by an air/glass/water boundary. The holographic emulsion is therefore unaffected by adverse aquatic conditions

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.

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts
Digital Presentation and Preservation of Cultural and Scientific Heritage, 2014 Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by ...

Interactive holographic stereograms with accommodation cues [PDF]
SPIE Proceedings, 2010 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
