The laser chamber module includes two laser light sources producing laser light emissions at wavelengths ?1 and ?2, respectively. Each beam path optionally includes an optical isolator. The beam paths enter the housing of the optical chamber module where they are combined into a third wavelength, ?. The housing of the optical chamber module includes an inlet and an outlet for passing a selected target gas. The gas sensor cell mates to the inlet of the housing. The target gas passes through the adjacent gas cell and into the optical chamber module through the inlet. The target gas exits the optical chamber module through the outlet. Within the optical chamber module, a nonlinear crystal receives the laser light emissions at wavelengths ?1 and ?2 and generates the third wavelength, ?3. The wavelength ?3 is selected to be at the mid-IR spectral absorption feature of the target gas, i.e.

  • Publication number: 20150090883
    Abstract: Methods, devices, and systems for imaging tissue and other samples or samples using infrared (IR) transmissions from coherent transmission sources, such as a wide range, tunable, quantum cascade laser (QCL) designed for the rapid collection of infrared microscopic data for medical diagnostics across a wide range of discrete spectral increments. The infrared transmissions are transmitted through, reflected from, and/or transreflected through a sample, and then magnified and/or focused prior to being detected by a detector. After detection, the sample related image data is used to assess the sample. Such methods, devices, and systems may be used to detect abnormalities in tissue, for example, before such abnormalities can be diagnosed using art cytopathological methods. The methods, devices and systems may also optionally include a visible light detection subsystem and/or a motion control subsystem to assist in control and processing of imaging.

  • Publication number: 20150090884
    Abstract: Compact opto-electronic sensor modules are described that allow detection of an object's motion occurring in spatial regions (e.g., quadrants) that are located primarily directly about the surface of a device in which the module is located. For example, light (e.g., infra-red) from a light emitting element in the module can illuminate substantially all, or at least a significant percentage of, areas in a plane directly above the surface of the device. Each of multiple light detecting elements in the module can be arranged to receive light from a respective detection zone directly above the surface of the device.

  • Patent number: 8993967
    Abstract: Probe light pulses output from a light source are input to an optical effect unit after the beam diameter is changed by a beam diameter changing optical system, the pulse front is tilted by a pulse front tilting unit, and the beam diameter is adjusted by a beam diameter adjusting optical system. To the optical effect unit, probe light pulses output from the beam diameter adjusting optical system are input, and an electromagnetic wave being an object to be detected is also input. Optical characteristics of the optical effect unit change due to propagation of the electromagnetic wave, and probe light pulses affected by the change in optical characteristics are output from the optical effect unit. The probe light pulses output from the optical effect unit are detected by a photodetector.

  • Patent number: 8981303
    Abstract: A sensor device has an optical waveguide containing an electro-optic crystal for propagating light, a coupler provided adjacent to the optical waveguide to propagate a terahertz wave generated from the electro-optic crystal as a result of the propagation of light in the optical waveguide, and a detector for detecting the terahertz wave propagating through the coupler or the light propagating through the optical waveguide. The terahertz wave is totally reflected in a section of the coupler opposite to a section where the coupler is adjacent to the optical waveguide while passing through and propagating in the optical waveguide, and in the total reflection section, the terahertz wave interacts with a subject placed close to the total reflection section.

  • Publication number: 20140374601
    Abstract: The embodiments of the present invention are directed to applying intimate contact pressures to samples while undergoing ATR infrared interrogation. As a general mode of operation, after a solid sample is placed on the ATR element, a force actuator moves an anvil arm to apply a contact force to the sample against the ATR. Thereafter, when the scan is over, the user can see the result of the one or more scans. The force actuator may be a motor or a solenoid or other type of force actuator. The applied contact force may be a fixed force or may be a user-selectable force or may be automatically controlled through feedback from the spectrometer based on the spectroscopic signature of the sample material.
