Fixed three-dimensional holographic images.

چکیده
Three-dimensional holograms were recorded in a cerium-doped, strontium barium niobate (SBN:75) photorefractive crystal. These holograms are shown to not degrade after more than one week of continuous readout and to reconstruct reproductions of the original object with an observable field of view of approximately 35 degrees.

Experimental evaluation of a full-color compact lensless holographic display.
An iterative phase retrieval method for a lensless color holographic display using a single light modulator is experimentally validated. The technique involves iterative calculation of a three-plane synthetic hologram which is displayed on a SLM simultaneously lit with three laser beams providing an RGB illumination. Static and animated two-dimensional flicker-free full color images are reconst...
متن کاملDynamic holographic 3-D image projection.
The display of dynamic holographic images is possible by computing the hologram of objects in a three-dimensional scene and then transcribing the two-dimensional digital hologram onto a digital micromirror system illuminated with coherent light. Proof-of-principle instruments that reconstruct real and virtual images are described. The underlying process, its characteristics, limitations and uti...
متن کاملAthermally photoreduced graphene oxides for three-dimensional holographic images
The emerging graphene-based material, an atomic layer of aromatic carbon atoms with exceptional electronic and optical properties, has offered unprecedented prospects for developing flat two-dimensional displaying systems. Here, we show that reduced graphene oxide enabled write-once holograms for wide-angle and full-colour three-dimensional images. This is achieved through the discovery of subw...
متن کاملThree-dimensional identification of stem cells by computational holographic imaging.
We present an optical imaging system and mathematical algorithms for three-dimensional sensing and identification of stem cells. Data acquisition of stem cells is based on holographic microscopy in the Fresnel domain by illuminating the cells with a laser. In this technique, the holograms of stem cells are optically recorded with an image sensor array interfaced with a computer and three-dimens...
متن کاملSimultaneous Measurement of 3d Interfacial Geometry and Internal Flow Structure of Micro Droplet Using Digital Holographic Microscopy
This paper aims to develop three-dimensional measurement method based on digital holographic microscopy (DHM) to investigate the droplet-based microfluidic phenomena. The advantage of DHM is the direct measurement method for the three-dimensional measurement target with single camera based on analysis of phase information of holographic images. Furthermore, we tried to measure two important inf...
