Abstract

Many thermal processes pass very quickly. The normal frame rate of radiometric scanners or FPA cameras is sometimes far below what might be needed in order to see what is happening with the object. When it comes to measurement there is nothing yet to match the measurement accuracy of the best scanning devices. When very high measurement accuracy has to be combined with highest possible data acquisition rate, the best way today is to use the scanning technique, with the scanner set for line scanning. Thus it is possible to acquire thermal information also from very fast processes. Computer processing of thermal information is today applied in almost 100% of the cases. If this is applied to thermal information, which is acquired by Fast line scanning, the results can be very interesting. This method has been successfully applied e.g. to tires, disk brakes, fusion research, and to analysis of explosions in connections with the development of air-bags. The paper describes the above mentioned applications. This includes a method description and some thermograms, which show the final result.
