Holographic displays have gained unprecedented attention as next-generation virtual and augmented reality applications with recent achievements in the realization of a high-contrast image through computer-generated holograms (CGHs). However, these show high energy concentration limited angular spectrum, whereas uniformly distributed spectrum suffer from severe speckle noise reconstructed images...

In time-averaged digital holography (TADH), one records a hologram of a periodically oscillating object by using the exposure time typically much longer than the oscillating period. Problems arise when the total available exposure time is restricted or when the oscillation period is unknown. In this work we investigate effects of short exposure time to the quality of the recorded hologram and s...

According to the holography principle (due to G. ‘t Hooft, L. Susskind, J. Maldacena, et al.), quantum gravity and string theory on certain manifolds with boundary can be studied in terms of a conformal field theory on the boundary. Only a few mathematically exact results corroborating this exciting program are known. In this paper we interpret from this perspective several constructions which ...

In order to understand the details of the flow field in the microand nanofluidic devices, it is necessary to measure the three-dimensional velocity field under a microscopy. Thus, the development of a new measuring technique for the three-dimensional velocity by a single camera is strongly needed. One solution is the use of holography, but it has been known that the resolution in the depth dire...
