TELOPS Articles & Applications Notes

  1. Hyperspectral Imaging Improves Surface Mine Mapping Processes
    11/15/2018

    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.

  2. How To Interpret Images From Infrared Cameras
    7/26/2018

    Real-life interpretations of infrared images from a variety of field applications may become complex. In order to make the most accurate interpretation, the camera user must know about the measurement conditions as well as have a good foundation in radiometry. 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.

  3. Radiometry 101
    7/26/2018

    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.

  4. New Technology Could Expand Thermography Capabilities
    4/30/2018

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

  5. Using High-Speed Infrared Imaging In Additive Manufacturing
    1/24/2018

    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.

  6. 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.

  7. Direct Imaging Of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral Imaging
    2/24/2017

    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.

  8. Infrared Imaging For Material Characterization In Fracture Mechanics Experiments
    8/15/2016

    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.

  9. High-Speed Infrared Imaging For Analysis Of A Diesel Engine Supplied With Premixed Methane-Air Charge
    6/10/2016

    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.

  10. 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.
