SWIR Cameras white papers and application notes

  1. Laser-Gated Imaging 8/24/2016

    Laser-gated imaging is a technique for night vision that detects and recognizes targets at long range without the need for any natural light sources. This article discusses its general principles, as well as the advantages of imaging in different spectral bands in visible and infrared light.

  2. Photoluminescence Testing Makes Better Solar Cells At Lower Costs 8/14/2013

    This white paper explains how NIR and SWIR cameras based off of InGaAs technology can be used for defect detection in in-line inspection of high-volume solar cell manufacturing lines.

  3. Detecting And Defeating Subversive Night And Fog Activities 4/8/2013

    Around-the-clock surveillance capability in any weather is a decisive operational ad-vantage for military and emergency services. In these and similar applications, SWIR cameras are well-suited for everyday use because they show good results when compared with other imaging technologies. To recognize and track objects of light-reflecting as well as self-radiating natures, SWIR cameras can be easily combined with thermal LWIR cameras and their images overlaid to enhance their content and validity.

  4. Application Note: Machine Vision: Key Tool For Efficient And Low-Cost Solar Cells 6/15/2011
    The cost of electricity produced from sunlight employing the photovoltaic (PV) effect is currently significantly higher compared to electricity produced from fossil fuels such as coal. By Xenics
  5. Application Note: SWIR Imaging In Solar Cell Inspection 12/29/2009
    Solar cells are large-area semiconductor devices with typical dimensions of 15 cm. Loss mechanisms such as locally reduced diffusion lenghts or parallel resistances often reduce the energy conversion efficiency of solar cells. Characterization techniques that can provide spatially resolved information about the performance of a solar cell therefore are important to manufacturers not only in research and development but also in solar cell production.

  7. Application Note: Cheetah-640CL For High Speed Imaging In SWIR 12/29/2009
    The laser beams used for free-space satellite communication emit typically at 1060 nm or 1550 nm (eye-safe and low atmospheric attenuation). In reduced region of interest mode of, e.g., 100 x 100 pixels, the Cheetah camera can achieve well over 10.000 fps. This feature of the camera is being used in adaptive optics systems to correct imaging systems for atmosphere turbulence. The high speed Cheetah camera, mounted behind a Shack-Hartmann sensor to measure the wave distortion, provides active feedback to the deformable telescope mirror in order to have a corrected wavefront on the highspeed demodulator.
