TLDR
A modified Gabor-like setup able to recover the complex amplitude distribution of the object wavefront from a set of inline recorded holograms is presented and superior results to the Gabor method are produced.Abstract:
We present a modified Gabor-like setup able to recover the complex amplitude distribution of the object wavefront from a set of inline recorded holograms. The proposed configuration is characterized by the insertion of a condenser lens and a spatial light modulator (SLM) into the classical Gabor configuration. The phase shift is introduced by the SLM that modulates the central spot (dc term) in an intermediate plane, without an additional reference beam. Experimental results validate the proposed method and produce superior results to the Gabor method.read more

What spatial light modulators can do for optical microscopy
TL;DR: In this article, a review of high-resolution miniature spatial light modulators (SLMs) in optical microscopy has been presented, which can be used to control and shape the sample illumination, or they can act as spatial Fourier filters in the imaging path.
Compressive holography

TL;DR: This work demonstrates single frame 3D tomography from 2D holographic data using compressed sampling, which enables signal reconstruction using less than one measurement per reconstructed signal value.

Full color natural light holographic camera
TL;DR: Full-color, three-dimensional images of objects under incoherent illumination are obtained by a digital holography technique based on self-interference of two beam-split copies of the object's optical field with differential curvatures based on a few mirrors and lenses, a piezo-actuator, and a color camera.

Phase-shifting digital holography
Ichirou Yamaguchi,Tong Zhang +1 more
TL;DR: A new method is proposed in which the distribution of complex amplitude at a plane is measured by phase-shifting interferometry and then Fresnel transformed by a digital computer, which can reconstruct an arbitrary cross section of a three-dimensional object with higher image quality and a wider viewing angle than from conventional digital holography using an off-axis configuration.

Reconstructed Wavefronts and Communication Theory
Emmett N. Leith,Juris Upatnieks +1 more
TL;DR: In this paper, a two-step imaging process is described from a communication-theory viewpoint, which consists of three well-known operations: a modulation, a frequency dispersion, and a square-law detection.

TL;DR: Three-dimensional holograms of transparencies produced in diffused light are of a quality comparable to pictures produced by conventional photography with incoherent light and have all the visual properties of the original scene.

Digital in-line holography for biological applications
TL;DR: Digital in-line holography with numerical reconstruction has been developed into a new tool, specifically for biological applications, that routinely achieves both lateral and depth resolution, at least at the micron level, in three-dimensional imaging.
