  1. Math, Magic And MTF: A Cheat Sheet For The Vision System Community
    4/19/2017

    MTF is the best proxy for lens performance, but the math behind it and the graphs that depict it often obstruct understanding. This paper demystifies MTF, arming vision system decision makers with the knowledge they need about it to choose the right lens every time.

  2. Hot Biology: Investigating The Thermal Physiology Of Birds And Mammals
    4/13/2017

    Many details of the thermal biology of animals are unknown. To fill the gaps in this knowledge, researchers at the Institute of Biodiversity, Animal Health and Comparative Medicine at the University of Glasgow, Scotland are using thermal imaging to learn as much as possible in order to help animals in the long run.

  3. FLIR Thermal Science Cameras Support Medical Research
    4/13/2017

    Tissue auto-fluorescence spectroscopy is used to differentiate between normal and diseased tissue. This technique measures the intrinsic light emissions from biological agents upon excitation by a light source, but the relationship between auto-fluorescence and temperature has not been well defined.

  4. Thermal Imaging Cameras Monitor The Quality Of Vessel Constructions
    4/13/2017

    Shipbuilding requires advanced, non-destructive testing methods to ensure the quality of the ship's construction, and therefore the quality of the fleet. This article describes how thermal imaging is used for things like vessel construction, surface inspection, detection of undercoat corrosion, quality control, and more.

  5. Assessing Infrared Spectrum Hyperpixel Array Imagers For Measuring Temperature In Additive And Subtractive Manufacturing
    4/13/2017

    This white paper discusses the use of infrared spectrum hyperpixel array imagers in additive and subtractive manufacturing temperature measurement, the issues that are involved, and the results of multiple analyses on the method.

  6. Nordic District Heating Networks Monitored From The Sky With Thermal Imaging
    4/13/2017

    According to some researchers, district heating is the cheapest method for a city to make cuts on carbon emissions. District heating is a system that distributes hot water or steam to a centralized residential or commercial location through an underground network of pipes. Maintaining a large district heating network can be a difficult task, so to help large Scandinavian cities to effectively monitor and maintain their district heating networks, the company Termisk Systemteknik has developed a district heating scanning system from the sky, based on thermal imaging cameras from FLIR Systems.

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

    The semiconductor industry has grown to cover a wide variety of applications such as those with memory integrated circuits for PCs or mobile devices, solar cells, and many more electronic devices. Within the semiconductor industry, SWIR cameras can be used for inspecting the quality of pure semiconductor material after ingot growth, the alignment of a saw blade or laser, failure analysis, and other semiconductor inspection applications. 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.

  8. Choosing Laser Modules For Industrial Image Processing
    4/7/2017

    A light-cutting process is a technique used for measuring profiles, high differences, and geometries based on the principle of laser triangulation with a system consisting of a lighting source, a camera, and evaluation software. 

  9. Volcanic Eruption Observations From An Elevated Point Of Stromboli Using Thermal Infrared Hyperspectral Imaging
    4/7/2017

    Research on different indicators of imminent volcanic eruptions is carried out on an ongoing basis, especially with volcanoes located close to urban areas. This app. note highlights the benefits of using standoff infrared hyperspectral imaging for characterizing volcanic process.

  10. How To Customize Glass For New Light-based Technologies
    4/5/2017

    The ability to control light is often the key to many new light-based technologies and products. Those seeking to push the limits of what light can achieve should consider how glass filters can be used to selectively filter light. Glass is a highly flexible material and can be engineered to either absorb or transmit specific wavelengths of light, and glass manufacturers are able to help engineer a custom glass solution for specific products. In this article, Kopp Glass shares the steps they take to develop a custom glass composition.
