IR Camera for Research, Science and Engineering
Experimental Mechanics
- Characterization of mechanical properties such as Young’s modulus, shear strain, viscosity and fracture toughness is very important in the development process of new alloys and composite materials. Researchers typically carry out many different measurements like tensile displacement tests, compression tests and fatigue tests using extensometer and split-Hopkinson bars setups. Infrared imaging allows to characterize the energy released by the investigated material as it undergoes elastic and plastic deformation up to the fracture point.
Combustion Analysis
- Most combustion reactions generate infrared-active gases such as carbon dioxides (CO2) and water vapor as well as known pollutants like carbon monoxide (CO) and nitrogen oxides (NOx). On this regard, infrared imaging represents an interesting diagnostic tool as it allows chemical imaging and temperature measurement at the same time. High-speed infrared imaging is useful for characterizing fuel injection, ignition and combustion in internal combustion engines (ICE), gas turbines or jet engines, regarding which lowering fuel consumption and soot generation represents an important research aspect.
