SWIR Cameras white papers and application notes

  1. Foreign Object Detection In Food Inspection And Sorting 5/16/2019

    Food inspection, in connection with automated sorting and classification methods, has become a major field of application for advanced image capture systems and infrared cameras. This case study tells how Xenics' line scan SWIR camera Lynx is used for complex imaging tasks.

  2. Short-Wave Infrared Temporal Multiplexing For Cost-Effective Multispectral Solutions 6/19/2018

    Temporal multiplexing is an alternative approach to hyperspectral imaging that uses a fast LED technology. Instead of broadband illuminating and diffracting the spectrum of light in the camera, a broadband sensitive chip is used, and the illumination spectrum is varied over time via fast triggering.

  3. Short-Wave Infrared Cameras In Semiconductor Inspection Applications 4/13/2017

    This white paper discusses several applications of SWIR (short-wave infrared) cameras within semiconductor inspection applications, especially those that rely on the capability of SWIR cameras to see through semiconductor materials, such as silicon.

  4. Short-Wave Infrared Adaptive Optics And Applications 2/23/2017

    This article introduces adaptive optics and the benefits of using (short-wave) infrared cameras in wavefront sensing for applications including astronomy, laser communication, biological imaging microcopy, and retinal imaging in combination with optical coherence tomography.

  5. SWIR Camera Utilized In Cutting Edge Tornado Research 2/2/2017

    A team of researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department recently tested the practicality of using shortwave infrared (SWIR) imaging for improving the detection of poorly-visible tornadoes in supercell thunderstorms. 

  6. 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.

  7. SWIR And The U-2 8/4/2016

    The U-2 spy plane is the leading reconnaissance platform for the United States. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light).

  8. The Third Infrared Window 8/4/2016

    Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging. 

  9. NIR InGaAs Pixel Chip Fabrication 8/4/2016

    InGaAs pixel chips are utilized in products like 2D NIR/SWIR cameras, NIR/SWIR linear arrays, and avalanche photodiodes. This app note presents the process of creating NIR pixel chips, starting at the crystal growth of semiconducting InGaAs on an InP substrate wafer to the product inspection.

  10. Short Wave Infrared Enhances Machine Vision 10/23/2013

    SWIR (short wave infrared) imaging is especially useful for measuring, monitoring, and controlling the reliability and quality control aspects of manufacturing and industrial processes.
