Patent number: 6226083Abstract: 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.Type: GrantFiled: May 5, 1999Date of Patent: May 1, 2001Assignee: Georgia Tech Research CorporationInventors: Robert E. Schwerzel, Nile F. Hartman

Patent number: 5252450Abstract: 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.Type: GrantFiled: February 6, 1991Date of Patent: October 12, 1993Assignee: Battelle Memorial InstituteInventors: Robert E. Schwerzel, Kevin B. Spahr

Patent number: 4571377Abstract: 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.Type: GrantFiled: January 23, 1984Date of Patent: February 18, 1986Assignee: Battelle Memorial InstituteInventors: Vincent D.

Patent number: 4435828Abstract: 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).Type: GrantFiled: April 14, 1982Date of Patent: March 6, 1984Assignee: Battelle Development CorporationInventors: Harold M. Epstein, Robert E. Schwerzel, Paul G. Andrus

Patent number: 4317994Abstract: 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).Type: GrantFiled: December 20, 1979Date of Patent: March 2, 1982Assignee: Battelle Memorial InstituteInventors: Philip J. Mallozzi, Harold M. Epstein, Robert E. Schwerzel, Bernerd E. Campbell
