  • Patent number: 6226083
    Abstract: An integrated-optic spectrometer is disclosed for analyzing the composition of light reflected off a sample under analysis. In a simplified embodiment, the spectrometer includes a buffer, located on the top of a substrate, which is etched to create a diffraction grating having grating lines. The diffraction grating and grating lines are formed to provide diffraction of discrete wavelengths of light, while providing for maximum transmission of non-diffracted wavelengths. A waveguide is fabricated on top of the etched buffer through which the reflected light is directed. A photodiode detector array is located above the waveguide into which the diffracted wavelengths are diffracted, providing an analysis of the composition of the reflected light. A clad encompasses the integrated-optic spectrometer, thereby providing protection from outside interference.

  • Patent number: 5252450
    Abstract: A photochromic composition for incorporation into a light-transmitting polymer is described. Silver halide crystallites are capped with an organic capping group using multivalent metal ions integrated into the surface of the silver halide crystallite to provide crystallite surface sites that provide a handle between the organic capping group and the silver halide crystallites. The size of the capped silver halide crystallites are less than about 1000 .ANG.. A reverse micelle technique is used to control the size of the silver halide crystallite while integrating the multivalent ions and bonding the organic capping group. The capped crystallites are soluble in organic solvents and, as such, are readily incorporated into a polymer matrix.

  • Patent number: 4571377
    Abstract: Disclosed is a photopolymerizable vehicle and method for the selective photopolymerization of said vehicle by the application of a plurality of different selected wavelengths of energy wherein any single wavelength of energy is inadequate for effecting said photopolymerization. The method comprises sequentially applying a plurality of different selected wavelengths of energy to said vehicle whereby polymerization is effected at the intersection of said wavelengths of energy.

  • Patent number: 4435828
    Abstract: Apparatus (10) for obtaining fluorescence laser EXAFS (Extended X-ray Absorption Fine Structure). A lens (12) directs a pulse of radiant energy (13) onto a metal target (15) to produce X-rays (16). A baffle (17) directs the X-rays (16) onto a spectral-dispersive monochromator (18) which directs the spectrally-resolved X-rays (16R) therefrom onto a sample (11). Fluorescence X-rays (27) from the sample (11) strike a phosphor (26) on a grid (19). Emitted light (21) from the phosphor (26) corresponds spatially to the spectral resolution of the X-rays (16R). Emitted light intensity at a point along the spatial distribution corresponds to the absorption characteristics of the sample (11) at a particular wavelength of the incoming X-rays (16R). An imaging lens (20) directs the emitted light (21) onto photographic film or an array detector (22).

  • Patent number: 4317994
    Abstract: Apparatus (10) for obtaining EXAFS data of a material (11). A lens (12) directs a pulse of radiant energy (13) from a laser (14) onto a metal target (15) to produce X-rays (16) of a selected spectrum and intensity at the target (15). A baffle (17) directs X-rays (16) from the target (15) onto a spectral dispersive monochromator (18) which directs the spectrally resolved X-rays (16R) therefrom onto a photographic film 20. A film of material (11) is located in the path (22) of only a portion (16L) of the X-rays (16) throughout a selected spectral band, and the resolved X-rays (16R) directed onto the photographic film (20) form two separate images thereon comprising a reference spectrum (26R) representative of a portion of the X-rays (16U) throughout the selected band that was not affected by the film of material (11) and an absorption spectrum (26A) representative of a portion of the X-rays (16L) throughout the selected band that was modified by transmission through the film of material (11).

  • Patent number: 4004571
    Abstract: An invention relating to photochemical collection, storage, and retrieval of solar energy through exposing to solar energy in the visible light spectrum of a photochemical valence isomerizable composition for a time converting a significant portion thereof to an intramolecular strained ring structure of higher energy content, retaining the higher energy content intramolecular strained ring structure until energy release is desired therefrom, and subsequently initiating conversion of the higher energy content intramolecular strained ring structure to its initial molecular structure through application of heat and/or catalyst thereto with a resultant exothermic conversion releasing heat in excess of that requisite for initiating and continuing the conversion and with the heat in excess thereof available for useful thermal applications; in the preferred method embodiment employing an organic valence isomerizable compound of a structure which includes two reactive carbon-to-carbon double bonds oriented in relatio

  • Patent number: 4004572
    Abstract: A process for photochemical collection, storage, and retrieval of solar energy, including solar energy in the visible and near-infrared light spectrum, comprising: exposing to solar radiation of a trans-isomer of particular geometrically isomerizable compounds, while dissolved in a predominantly (greater than 50 percent by volume) aqueous liquid medium, to isomerize the trans-isomer to a thermodynamically less stable, but kinetically stable, cis-isomer of higher energy content, heating the produced cis-isomer to an activation temperature triggering exothermal conversion (or return) of the cis-isomer to the trans-isomer with release of thermal energy; and continuing exothermal conversion of cis-isomer to trans-isomer through use of a portion of the exothermically released thermal energy and transferring of another portion of the released thermal energy from the region of exothermal conversion for availability of this other portion for useful thermal energy applications; with the therein employed geometrical is
