More Information
Summary:The effect of conductive heat transfer on the quality of thermal images, obtained using microbolometer matrices, and also the effect of the thermal properties of the matrix material on the line scattering function, is investigated theoretically and experimentally. The optimum value of the ratio of these properties to the size of the pixel element is determined. A thermal analysis of the numerical values of the detection and identification criteria is carried out. Areas for further research are pointed out and practical recommendations are given.
