TELOPS Articles & Applications Notes

  1. TESTD —The Telops Infrared Active Thermography Solutions

    Common 'intrusive' testing methods, while not technically destructive, are often messy, time-consuming, and render samples unusable for production. Non-contact testing and evaluation conducted via IR active thermography overcomes these hurdles.

  2. Hyperspectral Imaging Improves Surface Mine Mapping Processes

    Traditional methods of mapping surface mines have inherent challenges to obtaining data with enough detail to allow effective tactical and strategic decision making. Hyperspectral infrared imaging eliminates the problems.

  3. How To Interpret Images From Infrared Cameras

    This white paper will discuss how to establish a simple scene model in the field, how to determine their limitations, and how you can use these models to estimate physical parameters, such as the thermodynamic temperature of the objects being viewed.

  4. Radiometry 101

    Radiometry is the science of studying the transport of energy through radiation. In this article, Telops presents the basics of the principal laws of radiometry as seen through light-sensitive instruments.

  5. New Technology Could Expand Thermography Capabilities

    Thermography is an infrared (IR) imaging technology important in many fields. New advances address some conflicting limitations and improve results for research and testing.

  6. Using High-Speed Infrared Imaging In Additive Manufacturing

    Additive manufacturing involves extremely high thermal gradients that can sometimes induce stress and deformation in the materials. High-speed infrared imaging of this direct metal laser sintering (DMLS) process on stainless steel has been used to better understand and visualize these thermal transfers.

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

    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.

  8. Direct Imaging Of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral Imaging

    Many types of natural gas from shale formations are odorless, colorless, and highly flammable, and leaks/emanations are important considerations for safety and the environment. This application note illustrates the benefits of using an imager at a site where shale gas leaks unexpectedly happened.

  9. Infrared Imaging For Material Characterization In Fracture Mechanics Experiments

    When developing new materials, the characterization of mechanical properties becomes extremely important. This application note covers the process of performing tensile and shear tests on an variety of materials using high-speed and high-definition infrared imaging.

  10. High-Speed Infrared Imaging For Analysis Of A Diesel Engine Supplied With Premixed Methane-Air Charge

    Engineers are continuously looking to improve the efficiency of internal combustion engines (ICEs). This white paper walks through this experiment and investigates the different phases of the combustion cycle using four different spectral filters in order to see the difference in the exhaust fumes.
