TELOPS Articles & Applications Notes

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. Non-Destructive Testing Of Mid-IR Optical Fiber Using Infrared Imaging

    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.

  8. FAST Thermal Imaging – Tank/Artillery Muzzle Flash Analysis

    Typical large caliber muzzle flash last less than 0.2 seconds in the MW (3μm to 5μm) band. This fact leads to the most important technological challenge when it comes to the detection and characterization of short, millisecond long events: high frame rate.

  9. Urban Heat Island Characterization With Airborne Thermal Infrared Hyperspectral Imaging

    . This application note discusses how to efficiently characterize urban heat islands using airborne TIR hyperspectral imaging, and to better understand their relationship with man-made materials.

  10. Time-Resolved Multispectral Imaging Of Combustion Reactions

    Most combustion gases selectively absorb/emit infrared radiation over a very narrow spectral range, so spectral filters are used to estimate these parameters and provide selectivity of the combustion gases’ chemical nature. Telops developed a time-resolved multispectral to characterize combustion experiments, and measure temperature profiles. This application note illustrates how the Telops’ MS-IR MW was used to calculate the combustion profile of a lit candle.
