In recent years, cooled mercury cadmium telluride (MCT) infrared detector technology has made it possible for researchers to develop high performance infrared cameras for use in many demanding thermal image capture applications. The infrared cameras with this technology are being used in shortwave, mid- and long wave spectral band devices. The advancements also allow for high frame rate imaging and adjustable exposure times.
Infrared cameras are used in security settings and the cameras are designed to operate within various spectral bands which can be manipulated through the use of differing alloy compositions. This will result in an infrared camera that operates at maximum efficiency and detect even miniscule levels of infrared signals. The reason for choosing varying spectral bands for infrared cameras is that there are applications, including spectroscopy, laser beam viewing detection, cold-object imagining and marine environmental surveillance. The dynamic ranges vary wildly and the range able to be configured with these new infrared cameras makes them useful in many applications.
The array of pixel sizes and various resolutions allow the high speed infrared camera to be operational even in low light settings. Capturing fast moving thermal objects is a use for a high speed camera. This thermal event capturing is ideal for use in turbine blade analysis, airbag deployment, the study of heating effects of explosives and others. In these applications, the high speed infrared camera provides analysis of the events (i.e. airbag deployment) that would not be visible to the naked eye.
With the MCT infrared camera set in snapshot mode the images are simultaneously integrated through the thermal radiation emitted by the objects being observed. The advantages of the MCT detector and the enhanced digital imaging process make it possible for infrared cameras to capture and transmit and lead to the testing of high speed events. The ability to do this allows researchers the information necessary to recalibrate items, if necessary. In the past, researchers had to choose between time integration and motion blur; the newer infrared cameras make that compromise unnecessary. When used in airbag deployment testing, as an example, it allows manufacturers to test both safety and effectiveness and address issues with both.
