Holographic enhanced remote sensing system [PDF]
The Holographic Enhanced Remote Sensing System (HERSS) consists of three primary subsystems: (1) an Image Acquisition System (IAS); (2) a Digital Image Processing System (DIPS); and (3) a Holographic Generation System (HGS) which multiply exposes a ...

360-degree tabletop electronic holographic display
Optics Express, 2016 We demonstrate a tabletop holographic display system for simultaneously serving continuous parallax 3.2-inch 360-degree three-dimensional holographic image content to multiple observers at a 45-degree oblique viewing circumference. To achieve this, localized viewing windows are to be seamlessly generated on the 360-degree viewing circumference.

Characterizing and tracking single colloidal particles with video holographic microscopy
, 2007 We use digital holographic microscopy and Mie scattering theory to simultaneously characterize and track individual colloidal particles. Each holographic snapshot provides enough information to measure a colloidal sphere's radius and refractive index to ...

Real-time digital holographic microscopy observable in multi-view and multi-resolution
, 2010 We propose a real-time digital holographic microscopy, that enables simultaneous multiple reconstructed images with arbitrary resolution, depth and positions, using Shifted-Fresnel diffraction instead of Fresnel diffraction.

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 ...

Three dimensional tracking of gold nanoparticles using digital holographic microscopy
, 2011 In this paper we present a digital holographic microscope to track gold colloids in three dimensions. We report observations of 100nm gold particles in motion in water. The expected signal and the chosen method of reconstruction are described.
