Characterization of Small - Arms Muzzle Flash Using High - Speed Thermal Infrared Imaging

Muzzle flash analysis refers to the collection and exploitation of signatures generated by the expulsion of combustion gases from the muzzle produced during the discharge of a firearm. Muzzle flash characteristics are highly dependent upon attributes of both the firearm and ammunition including firearm make and model, barrel length, ammunition caliber and grain. Characterization of small arm...

Synchronous Full-Field Strain and Temperature Measurement

High temperature is a critical concern for most testing in the automotive, aerospace, and energy industries. Thermal expansion is an ever-present challenge, often making it difficult to distinguish strains caused from mechanical load from those originating solely due to material temperature change. Moreover, material deformation and its surface temperature change are strongly coupled because...

Remote Estimation of Sulfur Content in Fuel from SO2 Quantification from Ship Exhaust Plume

Sulfur oxide (SOx) from seagoing ships contribute to local air pollution in cities and coastal areas around the world. Sulfur dioxide (SO2) emissions in particular, are a precursor to acid rain and atmospheric particulates leading to ocean acidification which can contribute to negative human health outcomes. The International Convention for the Prevention of Pollution from Ships (MARPOL) def...

Airborne Thermal Infrared Hyperspectral Imaging for Mineral Mapping and Urban Heat Island Characterization

Minerals such as quartz, silicates, aluminosilicates (feldspar), magnesium silicates (serpentine) and olivines are among the most commonly encountered in the environment. Airborne mineral mapping of these minerals using conventional visible-near infrared (VNIR, 0.4-1.4 μm) and shortwave infrared (SWIR, 1.4-3 μm) sensors can be very challenging since the Si-O bounds are featureless or exhibit...

Space Probe Fluid Dynamics

Infrared camera mounted on a fast trajectory tracker system was used to capture infrared imagery of a model space probe travelling at supersonic velocities. In addition to the laminar-to-turbulent transition boundary, the infrared camera was able to detect shock waves and present a time dependent view of the flow field. Readily available infrared technology has the capability to provide deta...

Using High-Speed Infrared Cameras to Study Fire Spread

Scientists have developed several theoretical models to better understand and predict various aspects of wildfire behaviour. However, the lack of experimental data from real wildfire renders the validation of the models difficult and thus limits their applicability. More validation data would enable a better characterization of the valid boundaries within which the models can be applied. The...

Thermal Infrared Hyperspectral Imaging of Methane Landfill Emissions

Methane (CH4) and carbon dioxide (CO2) are landfill gases (LFG) originating from the decomposition of organic material as encountered in landfill areas. Both gases are considered greenhouse gases due to their high propensity for absorbing and emitting infrared radiation. For this reason, landfill installations are often equipped with wells and pumping systems to collect these LFGs. Depending...

Using High-Speed Infrared Cameras for Fire Turbulence Measurements

Wildfire spreads by pre-heating unburnt fuels (vegetation) using a combination of radiative and convective heating processes. In rapidly spreading grass or stubble wheat fuels, turbulent wind flow aids to intermittently convect the heat produced by combustion onto the unburnt fuels leading to its ignition and fire spread. In a way, the fire is sustaining its motion, but the role of atmospher...

Measurement of Supersonic Micron Size Cold Spray Particles

The extraction of both velocity and temperature of particles during the cold spray (CS) process using a high-speed, high-definition infrared (IR) camera was demonstrated by Nastic, A. & Jodoin, B.1. Following the success of this project, Telops worked with the University of Ottawa to address the challenges of measuring the speeds and temperatures of smaller cold spray particles (as small...

Measurement of Gas Temperature and Concentration Profiles Resulting from Detonation of TNT Using High Speed Hyperspectral Camera

The measurement of physical properties of expanding gases in the infrared region following a high-explosive detonation requires cameras having both high framerate and fine spectral resolution. Moreover, an accurate gas model is required to adequately explain and quantify the rapidly-evolving events based on properly-interpreted gas emissivity signatures. To achieve this goal, a Telops MW Fas...
