A new method for reconstructing whole optical wave fields with correct intensity and phase is presented which is based on the interference of two mutually coherent phase fields modulated by two spatial light modulators of the liquid crystal on silicon type. Contrary to classical holography this approach does not reconstruct twin images, thus it is a promising candidate for future holographic 3D-TV.
This paper describes experimental demonstration of holographic 3D reconstructions with a directly-viewing, transmissive, amplitude-modulating 5.5″ LCD SLM device in monochrome. A full-complex field modulation is achieved by the single amplitude-modulation SLM module using the Burckhardt-encoding scheme at the cost of the decrease in sampling. We define an effective holographic contrast ratio for the...
Digital holographic microscopy which has established itself as one of the leading techniques for quantitative phase contrast imaging. It has many advantages over conventional microscopy such as, improvement in image contrast and providing thickness profile of the object along the propagation direction of the probe beam. Other advantages are that numerical focusing and lensless imaging are possible...
Holographic interferometry as a means for nondestructive testing of technical or biological components has got significant momentum by the introduction of digital holography. In this paper after an introduction to holography, holographic interferometry and digital holography practical examples from deformation analysis, form determination, refractive index measurement, and wave front reconstruction...
In this paper we introduce a digital holographic technique called optical scanning holography (OSH). In OSH, the object to be measured is raster scanned by a pre-generated time-varying interference pattern. In addition, a single-pixel detector instead of an arrayed detector is used to acquire the hologram data. By using heterodyne technique in conjunction with synchronous demodulation, a complex hologram...
Our recent progress in dynamic holographic 3D display is introduced, including compressive holographic 3D display, full-color holographic 3D display, medium for holographic 3D applications, occlusion culling algorithm and improved full analytical polygon-based method.
We propose a method to combine two phase-shifted holograms into a complex hologram. The reconstruction of the complex hologram will have no twin image noise but have a constant zeroth-order beam, which could be attenuated by subsequent optical filtering of the reconstructed image.
