33. From “Guess” To “Best”: How Infrared Cameras Are Increasing Accuracy And Insight In Product Testing 5/25/2016

    This article explores how infrared (IR) cameras deliver a major data-gathering advantage over legacy approaches to temperature measurement, an advantage that can prevent costly product failures and safety hazards, providing an immediate and ongoing return on investment.

34. Non-Destructive Testing Of Mid-IR Optical Fiber Using Infrared Imaging 3/18/2016

    Some materials used in the manufacture of optical fiber lasers cannot have any defects if the laser system is to be efficient. This app note shows how infrared imaging can be used to carry out NDT of optical fiber integrity. The methodology allows the screening of tens of meters in just a few seconds.

35. High-Speed Thermal Cameras: The Need For Speed 9/15/2015

    The two types of thermal cameras include the cooled photon-counting cameras, and the uncooled microbolometer-based cameras. This application note discusses the different features and uses of these cameras, as well as providing real life examples of their fast and reliable measurement capabilities.

36. With Thermal Cameras, Image Matters 8/26/2015

    Not all thermal security cameras are created equal. If and when professionals look to purchase a thermal imaging camera, there are a whole set of specifications and performance parameters that may be unfamiliar. Instead of basing a decision on the analysis of specifications, take time to see the image quality for yourself, because image quality matters. This case study discusses how a thermal imaging camera’s resolution is typically measured, and why it is important to know for making the right thermal camera choice.

37. Standoff Midwave Infrared Hyperspectral Imaging Of Ship Plumes 8/5/2015

    Characterization of ship plumes is very challenging due to the great variety of ships, fuel, and fuel grades, as well as the extent of a gas plume. In this work, imaging of ship plumes from an operating ferry boat was carried out using standoff midwave (3-5 m) infrared hyperspectral imaging. Quantitative chemical imaging of combustion gases was achieved by fitting a radiative transfer model. Combustion efficiency maps and mass flow rates are presented for carbon monoxide (CO) and carbon dioxide (CO2). The results illustrate how valuable information about the combustion process of a ship engine can be successfully obtained using passive hyperspectral remote sensing imaging.

38. Airborne Thermal Infrared Hyperspectral Imaging For Mineral Mapping 8/5/2015

    In order to illustrate the benefits of thermal infrared hyperspectral imaging (HSI) for mineral mapping, an airborne survey was carried out over an open-pit mine in the Thetford Mines (Qc, Canada) area. The results show how high spectral resolution data facilitates temperature emissivity separation (TES) and atmospheric correction in order to retrieve a thermodynamic temperature map of the area and its associated spectral emissivity datacube. Mineral mapping of various minerals such as lizardite, serpentinite, and quartz was achieved through linear unmixing of the emissivity data using reference emissivity curves found in spectral libraries. The results illustrate the potential of TIR HSI for airborne mapping of silicate minerals.

39. Thermal Electronics Inspection Reaching Defect-Free Designs 7/14/2015

    In order to save a considerable amount of time and finances, Xenics thermal cameras can detect heat defects in electronics before qualification. These cameras can also optimize a working instrument’s life cycle when used in critical control of heat dissipation. This application note describes how Gobi thermal imaging cameras can be used in PCB prototyping and repair, and in verifying thermal designs in power electronics motor drives.

40. Cooled vs. Uncooled Thermal Imaging 4/29/2015

    This application note describes the difference between cooled and uncooled thermal imaging cameras, and when to use them in applications such as industrial R&D, academics and research, and defense and aerospace.
