Lock in thermography wikipedia

WitrynaInfrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the … WitrynaIn the eighties-nineties some attempts were made to adapt conventional lock-in procedures to thermography so that modulated thermal fields could be controlled, i.e. the so called thermal waves. Pioneering work was performed at Reims and Marseille Universities [1,2]. Real-time lock-in thermography was later reported [3-5].
