| Disclosed is a method of producing a hologram through a two-beam laser interfering exposure process, which comprises emitting a coherent laser light with a pulse width (τ) ranging from greater than 900 femtoseconds to 100 picoseconds and a laser power of 10 μJ/pulse or more using a solid-state laser as a light source, dividing the pulses light from the laser into two beams, controlling the two beams temporally and spatially in such a manner that the two beam are converged on a surface of or inside a workpiece for recording a hologram while matching the respective converged spots of the two beams with one another temporally and spatially to create the interference therebetween so as to record a surface-relief hologram on the surface of the workpiece or an embedded hologram inside the workpiece in an irreversible manner. The present invention can solve a problem with a conventional process of recording a hologram in a non-photosensitive material in an irreversible manner using interfering femtosecond laser pulses, specifically, distortion in the waveforms of pulsed laser beams and resulting instability in recording of an embedded hologram due to a non-linear optical interaction between the femtosecond laser pulses and air/the material. | ||||||

| 26 | Spinning disc volume holographic memory | US819793 | 1997-03-18 | US5896359A | 1999-04-20 | Harold M. Stoll |
| A volume holographic memory has a spinning disk comprised of photorefractive medium, object beam optics configured to direct an object beam through the outer edge of the disk, and reference beam optics configured to simultaneously direct a reference beam through the outer edge of the disk. An angle multiplexer manipulates the reference beam to facilitate the formation of angle multiplexed volume holograms. The object beam and the reference beam cooperate within the photorefractive medium to sequentially form a plurality of sets of angle multiplexed volume holograms therein while the disk is spinning. A phase conjugator directs a conjugate reference beam back through the disk after the reference beam has previously passed therethrough, so as to form a conjugate object beam to facilitate read-out. Amplitude monitoring is provided to facilitate use of an exposure schedule. Path length monitoring assures consistent phase relationship between the object and reference beams for write and erase operations. Calibration of the angle multiplexer is provided. | ||||||
| 27 | Method of imaging through a scattering medium using coherent light | US880170 | 1992-05-06 | US5313315A | 1994-05-17 | Jack L. Feinberg; Alexander Rebane |
| In a conventional hologram, a photographic film records the interference pattern of monochromatic light, scattered from an object (20) to be imaged, with a reference beam of unscattered light. Illumination of the developed film with a replica of the reference beam then creates a virtual image of the original object. Molecular resonance may be used to record an interference pattern between light signals that arrive at different times, and with this technique create a hologram (10') with time resolution. Using a time reference pulse (16) as a "light shutter", holographic images may be recorded selectively, according to the time taken by light travelling from the object to the hologram. This method may be used to image an object obscured by a light-scattering medium. | ||||||

| A three-dimensional optical recording medium is made of a photo-induced refractive index-changing material or two-photons absorbing material, which is based on photo-dissociation or photopolymerization. An optical information recording apparatus comprises a device for loading a three dimensional recording medium; a device for generating a high coherent optical pulse or a train of partially-coherent optical waves; a device for splitting the optical pulse into two pulse components and causing the two pulse components to propagate in the recording medium from opposite directions to meet at a predetermined three-dimensional position; a device for converging a light beam in the recording medium into a parallel beam; and a device for discretely scanning the meeting position of the pulse components to ensure three-dimensional recording in accordance with information to be recorded. Optical pulses or a train of optical waves are permitted to meet at a predetermined three-dimensional position in such a three-dimensional recording medium whose refractive index changes according to light intensity, thus ensuring three-dimensionally information recording as a discrete distribution of refractive indices at high density. | ||||||

| The techniques, apparatus, material and systems are described for a portable camera device which can be attached to the camera port of a conventional transmission or reflection microscope for complex wave front analysis. At least one holographic element (BS, grating) splits the beam (s) containing the sample information in two beams (r,o) and filters (r′, o′) them. The proposed invention has a relaxed alignment sensitivity to displacement of the beam coming from the microscope. Besides since it compensates the coherence plane tilt angle between reference and object arms, it allows for creating high-visibility interference over the entire field of view. The full-field off-axis holograms provide the whole sample information. | ||||||

| A sensor for remotely detecting an object, the sensor comprising: a light source having a coherence length that is short relative to the distance between the sensor and the object; a splitter splitting the emitted light beam into an incident beam and a reference beam; a photorefractive crystal recording a hologram on interfering reception of the reference beam and of the reflected beam reflected by an object illuminated by the incident beam, and playing back the hologram in a diffracted beam that is re-emitted by the crystal by anisotropic diffraction under the effect of the reference beam; a detector recording information on receiving the diffracted beam; and a polarizing filter that eliminates the major fraction of the reflected beam as transmitted by the crystal on receiving the reflected beam; such that the detector receives only the diffracted beam from the crystal. Both the sensor and imaging systems incorporating the sensor enable measurements to be made through diffusing media. | ||||||

| A harmonic holography (H2) technique and system that combines holography and nonlinear optics that enables holographic recording of 3D images with femtosecond framing time are provided. The H2 technique records holograms with second harmonic (SH) signals scattered off specialized nanocrystals that are functionalized to label specific protein or other biomolecules in a living organism. The capability of generating second harmonic radiations is specific to materials with noncentrosymmetric crystalline structures only, and χ(2) vanishes for all other types of materials. Therefore, a sharp contrast is formed when particles of noncentrosymmetric structures are dispersed in a medium of other species, pumped at a fundamental frequency, and imaged at the second harmonic frequency. The new scheme described herein provides a sound basis for a new type of contrast microscopy with enormous potential in molecular biomedical imaging. | ||||||
