    Abstract: Surface roughness measurements are made by illuminating a surface with coherent light to generate a speckle pattern and studying characteristics of the speckle pattern. The disclosed techniques may be applied to measuring the surface roughness of skin or other biological surfaces. Skin roughness information may be used in the diagnosis of conditions such as malignant melanoma. Methods and apparatus for measuring the coherence length of optical sources involve extracting information about speckle patterns resulting when light from the optical sources interacts with a surface having a known roughness.

    Abstract: Apparatus for diagnosis of a skin disease site using spectral analysis includes a light source for generating light to illuminate the disease site and a probe unit optically connected to the light source for exposing the disease site to light to generate fluorescence and reflectance light. The probe unit also collects the generated fluorescence and reflectance light and transmits this light to a spectrometer to be analyzed. The spectrometer generates and displays spectral measurements of the fluorescence light and the reflectance light which in together assist the user in diagnosing the disease site. The apparatus makes use of a conventional personal computer using a plug-in spectrometer card to provide a compact and low costs system. The system performs combined fluorescence and reflectance spectral analysis in a quick and efficient manner to provide a powerful tool for dermatologic diagnosis.

    Abstract: A system for detecting cancerous or precancerous lesions directs light produced from a mercury arc lamp into an illumination guide of an endoscope. Autofluorescence light produced by the tissue under examination is divided into red and green spectral bands by a dichroic mirror. Light in the red and green spectral band is applied to a pair of image intensified CCD cameras. The output of the camera that receives light in the red spectral band is coupled to a red video input of a color video monitor. Light produced by the camera that receives light in the green spectral band is coupled to the blue and green video inputs of the video monitor. The system produces a false color display, whereby healthy tissue appears cyan in color and cancerous or precancerous lesions appear reddish in color. The image displayed allows the operator to see the lesions within the context of the underlying tissue structures. The color contrast is adjustable to account for the autofluorescence property changes from patient to patient and from location to location.

    Abstract: Near-infrared Raman spectroscopy can be applied to identify preneoplastic lesions of the bronchial tree. Real-time in vivo Raman spectra of lung tissues may be obtained with a fiber optic catheter passed down the instrument channel of a bronchoscope. Using prototype apparatus, preneoplastic lesions were detected with sensitivity and specificity of 96 and 91% respectively. The use of Raman spectroscopy apparatus and methods in conjunction with other bronchoscopy imaging modalities can substantially reduce the number of false positive results.
