Signal superimpose system of micro-scale thermal imaging applied to un-cooled infrared cameras

Signal superimpose technique utilized in a micro-scale thermal imaging has been developed recently [1]. In this study the applicability of this technique to un-cooled micro-bolometer IR detector arrays is precisely examined. The method of pixel-by-pixel temperature calibration with superimposed temperature signal and a pseudo-acceleration of the sampling frame rate with a synchronized signal are applied to the precise measurement of phase change phenomena and the determination of the heat transport properties of the organic and polymeric materials.
