    摘要： The invention relates to methods and devices for assessing one or more components of a selected tissue in an animal. The present invention permits non-invasive assessment of tissue components in a body structure containing multiple tissue types by assessing multiple regions of the animal's body for an optical characteristic of the tissue of interest and separately assessing one or more optical (e.g., Raman or NIR) characteristics of the tissue component for one or more regions that exhibit the optical characteristic of the tissue of interest.

    摘要： A chemical imaging system is provided which uses a near infrared radiation microscope. The system includes an illumination source which illuminates an area of a sample using light in the near infrared radiation wavelength and light in the visible wavelength. A multitude of spatially resolved spectra of transmitted, reflected, emitted or scattered near infrared wavelength radiation light from the illuminated area of the sample is collected and a collimated beam is produced therefrom. A near infrared imaging spectrometer is provided for selecting a near infrared radiation image of the collimated beam. The filtered images are collected by a detector for further processing. The visible wavelength light from the illuminated area of the sample is simultaneously detected providing for the simultaneous visible and near infrared chemical imaging analysis of the sample. Two efficient means for performing three dimensional near infrared chemical imaging microscopy are provided.

    摘要： The disclosure relates to method and apparatus for providing a mosaic image based on two or more sub-images. A method according to the disclosure includes irradiating a sample with light to thereby produce photons from the sample and forming two or more sub-images from the photons; the sub-images formed from photons of substantially the same wavelength. The plurality of sub-images of the sample can be combined in a mosaic-type formation to define an image of the sample. Similar images of the sample at different wavelengths can be combined to form a comprehensive mosaic image of the sample at all wavelengths.

    摘要： The disclosure provides methods, systems, and computer program products for detecting compounds of interest that are deposited on or associated with objects of interest. The compounds of interest are not limited and include drugs, alcohol, cannabis, narcotics, controlled substances as defined by state, federal, or international law, ammonium-based explosives, MGE-based explosives, toxic compounds, organic compounds, inorganic compounds, nerve agents, or biological compounds. The disclosure increases the speed and efficiency of processing hyperspectral images, especially on low-power or portable devices.

    摘要： The instant disclosure provides for medical imaging systems that may be used in conjunction with an intraoperative medical device, such as an endoscope. Generally, the disclosed medical imaging systems include an illumination source configured to generate illuminating photons for illuminating a biological sample. An optical signal modulator is configured to separate one or more of the illuminating photons and photons that have interacted with the biological sample into a first optical signal having first multi-passband wavelengths and a second optical signal having second multi-passband wavelengths. At least one detector is configured to detect one or more of the first optical signal and the second optical signal and generate at least one image data set. A processor is configured to analyze the at least one image data set. In some embodiments, the processor is configured to differentiate between structures of the biological sample, such as between an ureter and surrounding tissue.
