摘要： Method and apparatus for imaging objects in turbid media. In one embodiment, the method comprises illuminating at least a portion of the turbid medium with substantially monochromatic light of at least two wavelengths in the 600-1500 nm spectral range. A first of the at least two wavelengths is equal to a resonance wavelength for an optical property of an object in the illuminated portion of the turbid medium but is not equal to a resonance wavelength for the turbid medium. A second of the at least two wavelengths is not equal to a resonance wavelength for either the object or the turbid medium. Light emergent from the turbid medium following each of the foregoing illuminations comprises a ballistic component, a snake component and a diffuse component. A direct shadowgram image may be obtained by preferentially passing from the emergent light, following each illumination. the ballistic and snake components thereof and detecting the preferentially passed light. Alternatively, an inverse reconstruction image may be obtained by determining, following each illumination, the intensity of the diffuse component at a plurality of points in time and then using these pluralities of intensity determinations and a mathematical inversion algorithm to form an image of the object in the turbid medium. An image of the object with higher contrast and better quality may be obtained by using the ratio or difference of the images recorded with resonant light and non-resonant light.

摘要： There is a need for a compact instrument and microscope that maps the vibration fingerprints of biomolecules and chemicals in a sample such as brain, breast, cervix, and arteries. One can use spontaneous Raman scattering to accomplish this; however, the problem is low scattering efficiency to 10−5. With the availability of continuous wave diode laser at numerous wavelengths from 375 nm-1800 nm for parametric nonlinear difference vibrational mixing to enhance Stimulated Raman process within materials. A seed beam at Raman frequency is used with pump laser beam. In this way one can map in 2D and 3D images of the vibrations associate with disease changes. Scanning a pair of laser beams can map the location of vibrations within cells, smears, membranes, arteries, and tissues of animal and human.

摘要： Spatial frequency spectra from periodic, aperiodic and quasi-random structures in materials are shown and used to detect differences among objects via internal coding from the spatial frequencies. The method is applied to different grades of human tissues for a new form of histology and pathology, and to detect art forgeries and coding boxes, money and papers and gems. The randomness of material structures on surface and at depths near surface can be detected from the spatial spectrum. In tissue spectral features from normal to different stages of cancer in tissue for ex vivo and in vivo applications can be recognized by different spectral fingerprints content of the spatial frequency. Similarly, the painting for the strokes of artist is different. A new type of instrument is described to analyze materials as a Spatial Frequency Spectrometer.

摘要： Spectral optical imaging at one or more key water absorption fingerprint wavelengths measures the difference in water content between a region of cancerous or precancerous tissue and a region of normal tissue. Water content is an important diagnostic parameter because cancerous and precancerous tissues have different water content than normal tissues. Key water absorption wavelengths include at least one of 980 nanometers (nm), 1195 nm, 1456 nm, 1944 nm, 2880 nm to 3360 nm, and 4720 nm. In the range of 400 nm to 6000 nm, one or more points of negligible water absorption are used as reference points for a comparison with one or more key neighboring water absorption wavelengths. Different images are generated using at least two wavelengths, including a water absorption wavelength and a negligible water absorption wavelength, to yield diagnostic information relevant for classifying a tissue region as cancerous, precancerous, or normal. The results of this comparison can be used to identify regions of cancerous tissue in organs such as the breast, cervix and prostate.
