  • Patent number: 8518445
    Abstract: The present invention teaches how to change the skin color perception, mainly the facial color from red, blue or yellow to white appearance, using quantum and optical principles. By selecting the right size and material of particles compounded in cosmetic preparations and applying the preparations to the skin, the scattering and/or emission from micro- and nanoparticles can provide a complementary color or in proximity to that complementary color of the skin color. The mixture of the color provided by the particles and the reflected color from the skin will whiten the skin or make inconspicuous of the hyperchromic portion of the skin. The invention can also be used for other applications in which the particles can be applied to a surface or blended into a material, such as, for example, automobile paint, house paint, glass color and nail polish.

  • Patent number: 7706862
    Abstract: 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.

  • Publication number: 20060291042
    Abstract: The computer-controlled optical scanning high magnification microscope imaging system with a large field of view disclosed herein overcomes a previous inability to achieve simultaneous high magnification and large field of view in microscopes. The subject imaging system includes galvanometer scanners, a CCD camera and high brightness LED sources at different wavelengths for rapid acquisition of a large number of high-resolution segmented tile images with a magnification of 800× each. The numerous segmented tiles combine to form a larger viewing field of the target, resulting in a compound image with an effective enlarged viewing area of 1.6×1.2 mm2. The speed and sensitivity of the system make it suitable for high resolution image monitoring of a small segmented area of dimensions 320×240 ?m2 with a 4 ?m resolution. The microscope can zoom in on each segment of the target without lost of resolution to attain a great degree of spatial detail.
