“…There is no simple analytic solution to the 3-D spatial integral for a complex holographic grating inside the material. Barbastathis and Brady 30 simplified the 3-D spatial integral down to a one-dimensional integral by using paraxial and geometrical approximations. However, the formulas are still mathematically sophisticated, not physically intuitive, and hard to apply to different holographic geometries because of the specific geometry dependency in the formula.…”

“…28,29 When the abilities of selective wave-front processing and multiplexing are combined, volume holograms can achieve multidimensional tomographic imaging. 30,31 In this application, predesigned diffraction patterns are recorded as holograms inside the holographic material. Signals from an object with unknown wave front or information illuminate the holograms and are diffracted, filtered, and optically processed by the holographic pattern because of selective Bragg phase matching.…”

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 simulation. The second architecture uses an imaging lens and a transmission geometry hologram to achieve linear two-dimensional optical sectioning and imaging of a four-dimensional ͑spatial plus spectral dimensions͒ object hyperspace. Multiplexed holograms can achieve simultaneously three-dimensional imaging of an object without a scanning mechanism.

“…Hiura & Matsuyama [8] as well as Farid & Simoncelli [5] describe two related methods for estimating depth from multiple images captured using coded apertures using defocus. Volume holograms [2] have been used for four dimensional spatio-spectral imaging. Zomet & Nayar [19] proposed a volume of light attenuating layers that are controllable in space and time for a lensless imaging system and showed a variety of nonconventional imaging functionalities such as split field of view.…”

We analyze the modulation of a light field via non-refracting attenuators. In the most general case, any desired modulation can be achieved with attenuators having four degrees of freedom in ray-space. We motivate the discussion with a universal 4D ray modulator (ray-filter) which can attenuate the intensity of each ray independently. We describe operating of such a fantasy rayfilter in the context of altering the 4D light field incident on a 2D camera sensor. Ray-filters are difficult to realize in practice but we can achieve reversible encoding for light field capture using patterned attenuating mask. Two mask-based designs are analyzed in this framework. The first design closely mimics the angle-dependent ray-sorting possible with the ray filter. The second design [17] exploits frequency-domain modulation to achieve a more efficient encoding. We extend these designs for optimal sampling of light field by matching the modulation function to the specific shape of the band-limit frequency transform of light field. We also show how a hand-held version of an attenuator based light field camera can be built using a medium-format digital camera and an inexpensive mask.

“…Alternatively, multiplexed volume holographic imaging, which can be realized in a mechanically simple, robust, and inexpensive system, allows for imaging of multiple depths simultaneously. 25 Should the cost and technical challenges of in vivo OCT, confocal, or multiphoton imaging be overcome, adjunct volume holographic imaging for close examination of suspicious regions could be beneficial.…”

Abstract. Ovarian cancer is the most deadly gynecologic cancer, a fact which is attributable to poor early detection and survival once the disease has reached advanced stages. Intraoperative laparoscopic volume holographic imaging has the potential to provide simultaneous visualization of surface and subsurface structures in ovarian tissues for improved assessment of developing ovarian cancer. In this ex vivo ovarian tissue study, we assembled a benchtop volume holographic imaging system (VHIS) to characterize the microarchitecture of 78 normal and 40 abnormal tissue specimens derived from ovarian, fallopian tube, uterine, and peritoneal tissues, collected from 26 patients aged 22 to 73 undergoing bilateral salpingo-oophorectomy, hysterectomy with bilateral salpingo-oophorectomy, or abdominal cytoreductive surgery. All tissues were successfully imaged with the VHIS in both reflectance-and fluorescence-modes revealing morphological features which can be used to distinguish between normal, benign abnormalities, and cancerous tissues. We present the development and successful application of VHIS for imaging human ovarian tissue. Comparison of VHIS images with corresponding histopathology allowed for qualitatively distinguishing microstructural features unique to the studied tissue type and disease state. These results motivate the development of a laparoscopic VHIS for evaluating the surface and subsurface morphological alterations in ovarian cancer pathogenesis. © The Authors.
