  • Optical fiber probe and methods for measuring optical properties
    Patent number: 6678541
    Abstract: A probe for the characterization of optical properties, including scattering and absorption properties of a sample, such as medical and industrial samples, includes an illumination fiber to radiate light toward an object and at least two collection fibers to receive light diffusely reflected from the object. At least two of the collection fibers are spaced at different distances from the illumination fiber. A region of the sample is illuminated with light from the illumination fiber. A portion of the light is diffusely reflected by the region. A portion of the diffusely reflected light is received by the two or more collection fibers. The region is characterized based on an amount of light received by each of the collection fibers. When the method is used for medical purposes, the characterization of the region may be used to make a diagnosis.

  • Photochemotherapy dosimeter
    Patent number: 5527349
    Abstract: A photochemotherapy dosimeter for monitoring cumulative photochemotherapy radiation dosage. The photochemotherapy dosimeter includes an optical fiber having a chemical cell attached at one end thereof. The chemical cell contains a photobleachable chemical which can be in a solution or incorporated into a matrix material. Changes in the absorption of the photobleachable chemical are used to monitor the cumulative photochemotherapy radiation dosage. In use, the chemical cell of the photochemotherapy dosimeter is positioned near an abnormal tissue which is subjected to photochemotherapy treatment.
