Method and apparatus for optical Doppler tomographic imaging of fluid flow velocity in highly scattering media

Patent Nelson, John Stuart [Laguna Niguel, CA]; Milner, Thomas Edward [Irvine, CA]; Chen, Zhongping [Irvine, CA]

Optical Doppler tomography permits imaging of fluid flow velocity in highly scattering media. The tomography system combines Doppler velocimetry with high spatial resolution of partially coherent optical interferometry to measure fluid flow velocity at discrete spatial locations. Noninvasive in vivo imaging of blood flow dynamics and tissue structures with high spatial resolutions of the order of 2 to 10 microns is achieved in biological systems. The backscattered interference signals derived from the interferometer may be analyzed either through power spectrum determination to obtain the position and velocity of each particle in the fluid flow sample at each pixel, or themore » « less

Apparatus for and method of performing spectroscopic analysis on an article

Patent Powell, George Louis [Oak Ridge, TN]; Hallman, Jr., Russell Louis (Knoxville, TN)

An apparatus for and method of analyzing an article having an entrance and an exit in communication with the entrance. The apparatus comprises: a spectrometer having an emission source with a focal point; a plurality of mirrors; and a detector connected to the spectroscope. The emission source is positioned so that its focal point is substantially coextensive with the entrance of the article. The mirrors comprise: a first mirror positionable adjacent the exit of the article and a second mirror positioned relative to the other of said plurality of mirrors. The first mirror receives scattered emissions exiting the article andmore » « less

Laser apparatus and method for microscopic and spectroscopic analysis and processing of biological cells

Patent Gourley, Paul L [12508 Loyola, NE., Albuquerque, NM 87112]; Gourley, Mark F [7509 Spring Lake Dr., Apt. B1, Bethesda, MD 20817]

An apparatus and method for microscopic and spectroscopic analysis and processing of biological cells. The apparatus comprises a laser having an analysis region within the laser cavity for containing one or more biological cells to be analyzed. The presence of a cell within the analysis region in superposition with an activated portion of a gain medium of the laser acts to encode information about the cell upon the laser beam, the cell information being recoverable by an analysis means that preferably includes an array photodetector such as a CCD camera and a spectrometer. The apparatus and method may be usedmore » « less

Multiple-wavelength spectroscopic quantitation of light-absorbing species in scattering media

Patent Nathel, Howard [Albany, CA]; Cartland, Harry E [Livermore, CA]; Colston, Jr., Billy W. (Livermore, CA); ...

An oxygen concentration measurement system for blood hemoglobin comprises a multiple-wavelength low-coherence optical light source that is coupled by single mode fibers through a splitter and combiner and focused on both a target tissue sample and a reference mirror. Reflections from both the reference mirror and from the depths of the target tissue sample are carried back and mixed to produce interference fringes in the splitter and combiner. The reference mirror is set such that the distance traversed in the reference path is the same as the distance traversed into and back from the target tissue sample at some depthmore » « less

Method and apparatus for differential spectroscopic atomic-imaging using scanning tunneling microscopy

Patent Kazmerski, Lawrence L [Lakewood, CO]

A Method and apparatus for differential spectroscopic atomic-imaging is disclosed for spatial resolution and imaging for display not only individual atoms on a sample surface, but also bonding and the specific atomic species in such bond. The apparatus includes a scanning tunneling microscope (STM) that is modified to include photon biasing, preferably a tuneable laser, modulating electronic surface biasing for the sample, and temperature biasing, preferably a vibration-free refrigerated sample mounting stage. Computer control and data processing and visual display components are also included. The method includes modulating the electronic bias voltage with and without selected photon wavelengths and frequencymore » « less
