Aviation & Aerospace White Papers and Case Studies

41. White Paper: Expanding The Dynamic Range Of Short Wave Infrared (SWIR) Imagery
    1/22/2010
    Advances have been made in short wave infrared (SWIR) imaging technology to address the most demanding imaging and surveillance applications. Multiple techniques have been developed and deployed in Goodrich’s SWIR indium gallium arsenide (InGaAs) cameras to increase the dynamic range performance of standard, commercial off-theshelf (COTS) products.

42. Negative-Stiffness Vibration Isolation Gaining Popularity As The Need For Refined Imaging With Laser/Optical Systems Increases
    4/23/2009
    Laser and optical systems, whether used in academic labs or industry, are very susceptible to vibrations from the environment and these instruments frequently need vibration isolation. When measuring a very few angstroms or nanometers of displacement an absolutely stable surface has to be maintained upon which to rest the instrument. Any vibration, coupled into the mechanical structure of the instrument, will cause vertical noise and fundamentally an inability to measure these kinds of high resolution features. By Jim McMahon
43. Case Study: Uniform Radiance Source For Thermal-Vacuum Sensor Calibration
    10/1/2008
    Vacuum Compatible Luminance/Radiance Sphere designed for use in a vacuum chamber to carry out radiometric characterization and calibration of electro-optical sensors under simulated temperature and vacuum environment.
44. Case Study: Uniform Radiance Source For Thermal-Vacuum Sensor Calibration
    10/1/2008
    Vacuum Compatible Luminance/Radiance Sphere designed for use in a vacuum chamber to carry out radiometric characterization and calibration of electro-optical sensors under simulated temperature and vacuum environment.
45. White Paper: Design And Characterization Of Uniform Spectral Radiance Source For Test And Calibration Of Radiometers Used For KOPMSAT-3
    7/10/2008
    An application-specific uniform calibration source is described. The biggest challenge in developing the system is to achieve 25% higher spectral radiance values than the Earth’s spectral radiance, with the lowest wavelength being the hardest to meet. This pre-flight test equipment will be used for characterization and calibration of imaging radiometers which will be used as satellite-borne remote sensors for KOPMSAT-3. The integrating sphere-based system will be used as a spectral radiance standard
46. Non-Invasive Biomedical Imaging With FD-OCT
    6/16/2008
    Current medical practice poses a constant demand for development of non-contact, minimally invasive imaging techniques that can be used in clinics and hospitals for early diagnostics of various diseases and as an alternative to standard excisional biopsy.
47. White Paper: Non-Invasive Biomedical Imaging With FD-OCT
    6/16/2008
    Current medical practice poses a constant demand for development of non-contact, minimally invasive imaging techniques that can be used in clinics and hospitals for early diagnostics of various diseases and as an alternative to standard excisional biopsy. Optical coherence tomography (OCT) is a relatively novel imaging method that allows for non-invasive, cross-sectional imaging of the biological tissue structure with cellular level resolution and at depths of up to 1.5–2 mm below the surface.
48. Measuring Cold Object Temperatures Using Infrared Cameras
    2/21/2008
    For cold targets a LWIR or VLWIR camera is superior to MWIR. Data and calculations in support of this position are given in this paper. Submitted by ElectroPhysics

50. Imaging In The Shortwave Infrared (SWIR) Spectrum Helps Track And Detect Lasers On The Battlefield
    2/21/2008
    As warfare becomes more asymmetric, civilians and other non-combatants become a larger percentage of the casualties, along with unintended property damage. The military, of course, hopes to avoid these types of casualties and destruction. With advancing technologies that enable more precision from their weapons, they also need better pointing and targeting capabilities, while remaining covert
