  • Patent number: 10502688
    Abstract: Provided are methods and systems for identification and analysis of materials and molecular structures. An apparatus for identification and analysis of materials and molecular structures may include a laser. The laser may, in turn, include an amplified spontaneous emission-suppressed single-frequency laser excitation source. The apparatus may further comprise a plurality of filters. The plurality of filters may include reflective volume holographic grating blocking filters. The apparatus may also comprise an optical unit and an optical spectrometer. The optical unit may be configured to deliver excitation energy to a sample substance and capture Raman signal scattering from the sample substance. The optical spectrometer may be disposed in a path of the Raman signal and configured to measure a spectrum of the Raman signal and generate a detection signal. Finally, the apparatus may comprise a processing unit configured to analyze the spectrum.

  • Publication number: 20190029560
    Abstract: A method and apparatus for preparing tissue of interest in a patient for possible excision by surgery. In one embodiment, the method comprises the steps of: removing a biopsy sample from the tissue of interest; placing a magnetic marker at the biopsy site; performing a pathology analysis of the biopsy sample; and if the pathology analysis indicates that the tissue of interest should be removed, locating the tissue for surgery using a magnetic detection probe. In one embodiment, the marker comprises magnetic nanoparticles in a bioabsorbable matrix. A system for preparing tissue of interest in a patient for possible excision by surgery. In one embodiment, the system includes a magnetic marker and magnetic detection probe system.

  • Publication number: 20170082489
    Abstract: Systems and methods are provided herein. An exemplary system may include a laser source, the laser source having a laser center wavelength; at least one narrowband optical element receiving light emitted by the laser, the narrowband optical element having a filter center wavelength, the narrowband optical element being arranged such that the filter center wavelength is initially spectrally aligned with the laser center wavelength, the filter center wavelength changing in response to a temperature change such that the filter center wavelength is not substantially aligned with the laser center wavelength; and a passive adjustment mechanism coupled to the narrowband optical element, the passive adjustment mechanism including an actuator, the actuator moving in response to the temperature change, the actuator motion rotating the narrowband optical element, the rotation compensating for the temperature change such that the filter center wavelength and laser center wavelength remain spectrally aligned.
