摘要： An assembly including an optically excited infrared nondestructive testing active thermography system is disclosed. The optically excited infrared nondestructive testing active thermography system includes one or more illumination sources, at least one first reflector, at least one second reflector and a computing resource. The at least one first reflector is arranged about the one or more illumination sources. The at least one first reflector has a near focal point and a far focal point. The one or more illumination sources is/are positioned at least proximate the near focal point of the at least one first reflector. The at least one second reflector is positioned at least proximate the far focal point. The computing resource is communicatively-coupled to a motor that is coupled to the at least one second reflector for manipulating the at least one second reflector between at least: a first spatial orientation and a second spatial orientation. At least one of the first spatial orientation and the second spatial orientation results in the at least one second reflector reflecting light that originates from the one or more illumination sources. The light is directed toward the at least one second reflector as a result of the light being directly propagated from the one or more illumination sources and reflected by the at least one first reflector. A method is also disclosed.

摘要： A method and apparatus for automated, non-destructive evaluation of spot welds includes a device for heating a sample containing a spot weld, an infrared camera for detecting changes in the surface temperature of the weld, and a computer to acquire and analyze data from the camera. In one embodiment, the sample is heated on one side and the time-temperature characteristic is monitored as the heat travels through the sample and the spot weld. The computer generates a histogram that represents the relationship between a particular time-temperature characteristic and the number of pixels exhibiting that characteristic, thereby representing the quality and size of the weld nugget. By generating a histogram corresponding to weld quality, the inventive apparatus and method provides an objective weld quality indicator and allows automation of the evaluation process.
