Infrared thermal imaging

The VIRTIS apparatus (Visible Infrared Thermal Imaging Spectrometer) on board can observe the atmosphere and the cloud layers at various depths (on both the day and the night side of the planet). VIRTIS has also provided data for the first temperature map of the hot Venusian surface. These data have led to the identification of hot spots and thus provided evidence for possible volcanic activity (www.esa.int/specials/venusexpress). 

Willson and Symyx have introduced an alternative infrared thermal imaging technique used for the screening of olefin polymerization catalysts. As with the thermistor technique, the technique is readily adapted to screen catalyst arrays, and exothermic events such as an olefin polymerization can be followed with exquisite sensitivity [14]. Thales Technologies have recently introduced a mecha-...

All transducers were monitored using a remote computer data acquisition system. There were separate video recordings (two to five cameras) made (Nind, 1996) as well as infrared thermal image records of the fireballs formed (Hawksworth and Brearley, 1996). British Gas additionally made wide- and narrow-angle thermal radiation measurements (Gosse and Pritchard, 1996). 

Direct thermal techniques, which include fiber-optic thermometry, theta-JC testing, infrared thermal imaging, and liquid crystal microthermography, either give a direct temperature measurement or a thermal resistance. 

The infrared thermal imaging is often used to investigate changes in skin surface temperature distribution and to monitor the physiology (Autonomous nervous and microvascular systems) in real time for clinical assessment purposes (Ring Ammer, 2012). Therefore, thermography was used in this experiment.

Infrared thermal imaging (thermographic) systems measure the self-emitted radiant energy from the surface of a target remotely and without contact, and produce thermal images in monochrome or color that characterize the distribution of surface temperature. Using the thermal distribution on the surface of a product sample as a measure of acceptability is only valid when thermal signatures of acceptable products have been studied, when standard acceptable patterns have been determined, and when maximum allowable deviations from these standards have been established. 

Imaging radiometer - An infrared thermal imager that provides quantitative thermal images. 

Infrared thermal imager - An instrument or system that converts incoming infrared radiant energy from a target surface to a thermal map, or thermogram, on which color hues or gray shades can be related to the temperature distribution on that surface. 

Thermograph - Another word used to describe an infrared thermal imager.

The detectors used for this focal plane array (FPA) are intended to be the same as are used for both the SIRTF FPA[1] 2tnd also for the Cincinnati Electronics 256 X 256 pixel infrared thermal imaging camera FPA. Thus, there is a considerable savings in cost and tedmology development realized, and consistent results can be obtsdned. 

Proper field monitoring and inspection techniques can be used to measure the real corrosion rate, to find safety risks on time and to avoid corrosion accidents. The field monitoring and inspection techniques normally include weight-loss coupons, electrical resistance probes, ultrasonic wall thickness measurements, infrared thermal imaging systems, etc. Ultrasonic wall thickness measurement is widely used to monitor the general and erosion corrosion rates of the equipment and pipelines in crude oil processing plants.
