Quantification of CO2 Passive Degassing at Sulphur Banks from Kilauea Volcano using thermal Infrared Multispectral ImagingVolcanic carbon dioxide (CO2) emission rates play an important role for assessing volcanic hazards and for constraining the role of magma degassing in the biogeochemical cycle of carbon. Quantification of CO2 emission rates from volcanoes remain challenging, mainly due to the difficulty of measuring volcanic CO2 against the high level of CO2 in the atmosphere. Thermal Infrared (TIR) imaging ...

Absolute Temperature and Emissivity Calculation Using a Multispectral Infrared Camera and n-Color TES Image ProcessingOver the past few years, two-color pyrometry has proven to be a fast and reliable non-invasive method to accurately determine the temperature of materials by overcoming emissivity issues usually encountered by thermal infrared cameras. However, the need for multiple independent cameras makes this method expensive to implement. In this work, a single Telops MS M100k equipped with a fast-rotat...

High-Speed Infrared Imaging of Metal Parts Fabrication by Additive ManufacturingAdditive manufacturing, also known as 3D printing, is considered by many to be the biggest industrial revolution since the Internet. This method allows rapid fabrication of metal pieces with various compositions, shapes and sizes. However, the extremely high thermal gradients involved in this fabrication process can induce stress and deformation in the materials. In an effort to better under...

Volcanic Eruption Observations from an Elevated Point of Stromboli Using Thermal Infrared Hyperspectral ImagingThe Stromboli volcano is well known for its periodic eruptions of small magnitude containing various proportions of ash, lava and gases. Imaging was carried out at a relatively high spectral and spatial resolution before and during eruptions from the North-East crater. Both sulfur dioxide (SO2) and silicon tetrafluoride (SiF4) could be successfully identified within the volcano’s plume from ...

High-Speed Infrared Imaging of a Split-Hopkinson Pressure Bar ExperimentIn order to illustrate this concept, high-speed infrared imaging was carried out at 13 000 frames per second during a split-Hopkinson pressure bar experiment on a polymer sample at the Structural Impact Laboratory (SIMLab) of the Norwegian University of Science and Technology. The results illustrate how high-speed infrared imaging can provide detailed information about the thermal properties...

Direct Imaging of Shale Gas Leaks Using Passive Thermal Infrared Hyperspectral ImagingThere are many types of natural gas fields including shale formations that are common especially in the St-Lawrence Valley (Canada). Since methane (CH4), the major component of shale gas, is odorless, colorless and highly flammable, in addition to being a greenhouse gas, methane emanations and/or leaks are important to consider for both safety and environmental reasons.
