20150316415 | SHORT-WAVE INFRARED SUPER-CONTINUUM LAERS FOR NATURAL GAS LEAK DETECTION, EXPLORATION, AND OTHER ACTIVE REMOTE SENSING APPLICATIONS - A system and method for using near-infrared or short-wave infrared (SWIR) light sources between approximately 1.4-1.8 microns, 2-2.5 microns, 1.4-2.4 microns, 1-1.8 microns for active remote sensing or hyper-spectral imaging for detection of natural gas leaks or exploration sense the presence of hydro-carbon gases such as methane and ethane. Most hydro-carbons (gases, liquids and solids) exhibit spectral features in the SWIR, which may also coincide with atmospheric transmission windows (e.g., approximately 1.4-1.8 microns or 2-2.5 microns). Active remote sensing or hyper-spectral imaging systems may include a fiber-based super-continuum laser and a detection system and may reside on an aircraft, vehicle, handheld, or stationary platform. Super-continuum sources may emit light in the near-infrared or SWIR. An imaging spectrometer or a gas-filter correlation radiometer may be used to identify substances or materials such as oil spills, geology and mineralogy, vegetation, greenhouse gases, construction materials, plastics, explosives, fertilizers, paints, or drugs. | 11-05-2015 |
20150305658 | NEAR-INFRARED LASERS FOR NON-INVASIVE MONITORING OF GLUCOSE, KETONES, HBA1C, AND OTHER BLOOD CONSTITUENTS - Non-invasive monitoring of blood constituents such as glucose, ketones, or hemoglobin A1c may be accomplished using near-infrared or short-wave infrared (SWIR) light sources through absorbance, diffuse reflection, or transmission spectroscopy. As an example, hydro-carbon related substances such as glucose or ketones have distinct spectral features in the SWIR between approximately 1500 and 2500 nm. An SWIR super-continuum laser based on laser diodes and fiber optics may be used as the light source for the non-invasive monitoring. Light may be transmitted or reflected through a tooth, since an intact tooth and its enamel and dentine may be nearly transparent in the SWIR. Blood constituents or analytes within the capillaries in the dental pulp may be detected. The non-invasive monitoring device may communicate with a device such as a smart phone or tablet, which may transmit a signal related to the measurement to the cloud with cloud-based value-added services. | 10-29-2015 |
20150305627 | SHORT-WAVE INFRARED SUPER-CONTINUUM LASERS FOR EARLY DETECTION OF DENTAL CARIES - A system and method for using near-infrared or short-wave infrared (SWIR) sources such as lamps, thermal sources, LED's, laser diodes, super-luminescent laser diodes, and super-continuum light sources for early detection of dental caries measure transmission and/or reflectance. In the SWIR wavelength range, solid, intact teeth may have a low reflectance or high transmission with very few spectral features while a carious region exhibits more scattering, so the reflectance increases in amplitude. The spectral dependence of the transmitted or reflected light from the tooth may be used to detect and quantify the degree of caries. Instruments for applying SWIR light to one or more teeth may include a C-clamp design, a mouth guard design, or hand-held devices that may augment other dental tools. The measurement device may communicate with a smart phone or tablet, which may transmit a related signal to the cloud, where additional value-added services are performed. | 10-29-2015 |
20150008344 | BROADBAND OR MID-INFRARED FIBER LIGHT SOURCES - An optical system for use in material processing includes a plurality of semiconductor diodes coupled to a beam combiner to generate a multiplexed optical beam. A cladding pumped fiber amplifier or laser receives the multiplexed optical beam and forms an intermediate beam having at least a first wavelength. An optical element receives the intermediate beam and forms an output beam with an output beam wavelength, wherein the output beam wavelength is at least in part longer than the first wavelength. A subsystem includes lenses or mirrors to deliver a delivered portion of the output beam to a sample. The delivered output beam has a temporal duration greater than about 30 picoseconds, a repetition rate between continuous wave and Megahertz or higher, and a time averaged intensity of less than approximately 50 MW/cm | 01-08-2015 |
20140236021 | NEAR-INFRARED SUPER-CONTINUUM LASERS FOR EARLY DETECTION OF BREAST AND OTHER CANCERS - A system and method for using near-infrared or short-wave infrared (SWIR) light sources for early detection and monitoring of breast cancer, as well as other kinds of cancers may detect decreases in lipid content and increases in collagen content, possibly with a shift in the collagen peak wavelengths and changes in spectral features associated with hemoglobin and water content as well. Wavelength ranges between 1000-1400 nm and 1600-1800 nm may permit relatively high penetration depths because they fall within local minima of water absorption, scattering loss decreases with increasing wavelength, and they have characteristic signatures corresponding to overtone and combination bands from chemical bonds of interest, such as hydrocarbons. Broadband light sources and detectors permit spectroscopy in transmission, reflection, and/or diffuse optical tomography. High signal-to-noise ratio may be achieved using a fiber-based super-continuum light source. Risk of pain or skin damage may be mitigated using surface cooling and focused infrared light. | 08-21-2014 |
20140188094 | FOCUSED NEAR-INFRARED LASERS FOR NON-INVASIVE VARICOSE VEINS AND OTHER THERMAL COAGULATION OR OCCLUSION PROCEDURES - Focused infrared light may be used in a non-invasive varicose vein treatment procedure with infrared light from a plurality of laser diodes that are combined in a multiplexer and coupled to a multi-mode fiber coupled to another fiber or fiber bundle that delivers the light to a lens/mirror assembly for application in the non-invasive procedures. The wavelength of light may be selected near 980 nm, 1210 nm, or 1720 nm to achieve a desired penetration depth and/or for absorption in a particular tissue type or water. Wavelengths near approximately 1100 nm, 1310 nm or 1650 nm may be advantageous for non-invasive procedures through the skin. The light may be focused with lower intensity on the skin or outer tissue to reduce collateral damage and higher intensity at a desired depth to induce thermal coagulation or occlusion at depths of about 1-2 mm or more. Surface cooling techniques, such as cryogenic sprays or contact cooling may be provided. | 07-03-2014 |
20140188092 | FOCUSED NEAR-INFRARED LASERS FOR NON-INVASIVE VASECTOMY AND OTHER THERMAL COAGULATION OR OCCLUSION PROCEDURES - Focused infrared light at wavelengths selected to target tissue below the skin may be used in a non-invasive procedure for vasectomies, varicose veins, hemorrhoids, or fungal nail infections. Infrared light from various sources selected for a particular application may be focused so that the cone of light has lower intensity on the skin/outer tissue and higher intensity at a desired depth to cause thermal coagulation or occlusion of the target tissue beneath the skin. Surface cooling techniques, such as cryogenic sprays or contact cooling may be used to protect the skin. More generally, the focused infrared light with or without surface cooling may be used in applications for thermally coagulating or occluding relatively shallow vessels while protecting or minimizing damage to outer layers of the tissue or skin. | 07-03-2014 |
20140183362 | SHORT-WAVE INFRARED SUPER-CONTINUUM LASERS FOR DETECTING COUNTERFEIT OR ILLICIT DRUGS AND PHARMACEUTICAL PROCESS CONTROL - A system and method for using near-infrared or short-wave infrared (SWIR) light sources for identification of counterfeit drugs may perform spectroscopy using a super-continuum laser to provide detection in a non-contact and non-destructive manner at stand-off or remote distances with minimal sample preparation. Also, near-infrared or SWIR light may penetrate through plastic containers and packaging, permitting on-line inspection and rapid scanning. The near-infrared or SWIR spectroscopy may also be used to detect illicit drugs and their chemical composition. Moreover, the spectroscopic techniques may also be applied to quality assessment and control in pharmaceutical manufacturing, thus permitting the implementation of smart manufacturing with feedback control. Fiber super-continuum lasers may emit light in the near-infrared or SWIR between approximately 1.4-1.8 microns, 2-2.5 microns, 1.4-2.4 microns, 1-1.8 microns. In particular embodiments, the detection system may be a dispersive spectrometer, a Fourier transform infrared spectrometer, or a hyper-spectral imaging detector or camera. | 07-03-2014 |
