Adaptive holographic interferometry for two-dimensional vibrational mode display

Incoherent Holographic Interferometry

Two-mode theory of BEC interferometry

A theory of BEC interferometry in an unsymmetrical doublewell trap has been developed for small boson numbers, based on the two-mode approximation. The bosons are initially in the lowest mode of a single well trap, which is split into a double well and then recombined. Possible fragmentations into separate BEC states in each well during the splitting/recombination process are allowed for. The B...

Projection-type see-through holographic three-dimensional display

Owing to the limited spatio-temporal resolution of display devices, dynamic holographic three-dimensional displays suffer from a critical trade-off between the display size and the visual angle. Here we show a projection-type holographic three-dimensional display, in which a digitally designed holographic optical element and a digital holographic projection technique are combined to increase bo...

Quickdraw3D – A front-end to a holographic three-dimensional display

Three-dimensional display devices attempt to present the user with a realistic scene. The realism involves the use of depth cues, so as to convince the user of three-dimensionality. Such display devices can be classified into those that require external aids such as glasses, and those that are viewable unaided. The latter are less cumbersome, and allow many viewers of the display. Holography fa...

Image Restoration with Two-Dimensional Adaptive Filter Algorithms

Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
