Volume holographic hyperspectral imaging.
A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and sensitivity. The first architecture uses the hologram directly as an objective imaging element where strong aberration is observed and confirmed by sim...
متن کاملVolume holographic spectral imaging
We report on a volume holographic imaging spectrometer (VHIS) system which allows retrieval of a scene's twodimensional spatial information as well as its spectral information. This is performed using a transmission volume hologram and a simple rotary scanning mechanism. The system has the advantages of high spectral and spatial resolutions and the potential of single-shot, four-dimensional (3D...
متن کاملOptical Design for a Spatial-Spectral Volume Holographic Imaging System.
Spatial Spectral Holographic imaging system (S(2)-VHIS) is a promising alternative to confocal microscopy due to its capabilities to simultaneously image several sample depths with high resolution. However, the field of view of previously presented S(2)-VHIS prototypes has been restricted to less than 200μm. This paper presents experimental results of an improved S(2)-VHIS design which have a f...
متن کاملInformation content of volume holographic imaging.
We discuss the general properties of optical imaging in three-dimensional object domains from an information-theoretic standpoint, expressing system performance in terms of imaging mutual information (IMI). We use IMI to characterize volume holographic imaging, a new optical imaging method with depth discrimination capability. The performance of this holographic method in imaging a simple discr...
متن کاملDesign and Construction of a New Holographic Optical Tweezers Apparatus
In the last decade, Atomic Force Microscopy (AFM) and Optical Tweezers (OT) have revolutionised molecular science by measuring picoNewton forces over lengthscales from 1 to 104 Å. Our research focuses upon experiments using the technique of OT, but we are also involved in theory and simulation that is complementary to these OT measurements. The OT apparatus is based upon a focused laser beam th...
