摘要：The results obtained from a simple analytic expression of the one dimensional heat conduction theory are compared with the results predicted by the numerical solution. The optimum of the pyroelectric film detector on a thick substrate is discussed. It is pointed out that the NEP of the optimized thick substrate-attached pyroelectric detector with 1 mu m thickness is close to NEP of a suspended pyroelectric detector with 10 mu m thickness.
