  • Patent number: 8892192
    Abstract: An apparatus for turbid sample measurement comprising a plurality of light sources for illuminating a turbid sample target area with non-spatial structured light, a projection system for illuminating the turbid sample target area with spatial structured light, a sensor for collecting light from the turbid sample target area, and a processor to analyze the data captured by the sensor to yield scattering and absorption coefficients of the turbid sample. A method comprises illuminating the sample with spatial structured light, collecting light reflected from the sample at a number of wavelengths, illuminating the sample with non-spatial structured light, collecting light reflected from the sample at a number of wavelengths, and combining the measurements of the collected light to obtain the optical properties of the sample and/or the concentration of absorbing or fluorescent molecules. The wavelengths of the spatial and non-spatial light sources are preferably different.

  • Publication number: 20100210931
    Abstract: A method of noncontact imaging for performing qualitative and quantitative analysis of wounds includes the step of performing structured illumination of surface and subsurface tissue by both diffuse optical tomography and rapid, wide-field quantitative mapping of tissue optical properties within a single measurement platform. Structured illumination of a skin flap is performed to monitor a burn wound, a diabetic ulcer, a decubitis ulcer, a peripheral vascular disease, a skin graft, and/or tissue response to photomodulation. Quantitative imaging of optical properties is performed of superficial (0-5 mm depth) tissues in vivo. The step of quantitative imaging of optical properties of superficial (0-5 mm depth) tissues in vivo comprises pixel-by-pixel demodulating and diffusion-model fitting or model-based analysis of spatial frequency data to extract the local absorption and reduced scattering optical coefficients.
