    摘要： A diagnostic system is provided with a plurality of semiconductor light emitters, each configured to generate an optical beam, and a beam combiner to generate a multiplexed optical beam. An optical fiber or waveguide communicates at least a portion of the multiplexed optical beam to form an output beam, wherein the output beam is pulsed. A filter, coupled to at least one of a lens and a mirror to receive at least a portion of the output beam, forms an output light. A beam splitter splits the light into a sample arm and a reference arm and directs at least a portion of the sample arm light to a sample. A detection system is configured to receive from the sample at least a portion of reflected sample light, to generate a sample detector output, and to use a lock-in technique with the pulsed output beam.

    摘要： A spectroscopy system includes a light source having an input light source, including semiconductor diodes generating an input beam with a wavelength shorter than 2.5 microns. Cladding-pumped fiber amplifiers receive the input beam and form an amplified optical beam having a spectral width. A nonlinear element broadens the spectral width of the amplified optical beam to 100 nm or more through a nonlinear effect forming an output beam that is pulsed. A filter is coupled to at least one of a lens and a mirror that receives the output beam and delivers the filtered output beam to a sample. A detection system includes detectors configured to receive the output beam reflected or transmitted from the sample. The detection system is configured to use a lock-in technique with the pulsed output beam and the spectroscopy system is adapted to detect chemicals in the sample.

    摘要： A system and method for selectively processing target tissue material in a patient include a laser subsystem for generating an output laser beam and a catheter assembly including an optical fiber for guiding the output laser beam. The beam has a predetermined selected wavelength between 900 nm and 2600 nm. The catheter assembly is sized to extend through an opening in a first part of the patient to a tissue material processing site within the patient. A beam delivery and focusing subsystem includes a focal distance, which may be adjustable, that positions the beam into at least one focused spot on the target tissue material disposed within a second part of the patient for a duration sufficient to allow laser energy to be absorbed by the target tissue material and converted to heat to produce a desired physical change in the target tissue material without causing undesirable changes to adjacent non-target material.

    摘要： A wearable device includes a measurement device having light emitting diodes (LEDs) measuring a physiological parameter. The measurement device modulates the LEDs to generate an optical beam having a near-infrared wavelength between 700-2500 nanometers. Lenses receive and deliver the optical beam to tissue, which reflects the optical beam to a receiver having spatially separated detectors coupled to analog-to-digital converters configured to generate receiver outputs. The receiver captures light while the LEDs are off, and reflected light from the tissue while the LEDs are on, to generate first and second signals, respectively. Signal-to-noise ratio is improved by differencing the first and second signals and by differencing the receiver outputs. The measurement device further improves signal-to-noise ratio of the reflected optical beam by increasing light intensity of the LEDs relative to an initial light intensity. The measurement device generates an output signal representing a non-invasive measurement on blood contained within the tissue.

    摘要： 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.
