Improve The Theoretical Analysis Of The Detection Rate Of Infrared Detector

In this paper, the pyroelectric detector set up the heat have both horizontal and vertical proliferation, the proliferation of a comprehensive theoretical model, derived a more general response formula; And in accordance with the general formula is derived under certain conditions, the responsiveness of the 10 kinds of device equations; Thus calculated can calculate the noise of these devices; Then according to the noise voltage and detection rates for the relationship between,to export 10 kinds of devices D*; analysis of how to improve the detection rate of the detector, and discussed closer to the ideal device structure.This content is divided into four parts of the system:The first part is the infrared system, a simple introduction, as well as the purpose and content of this article a simple overview of, as well as in military and civilian engineering applications; The second part into the pyroelectric detector responsive analysis, the establishment of a general responsiveness of the equation, after the 10 kinds of devices derived responsiveness equation; The third part of the first-degree equation derived according to response to the noise voltage, to obtain D*, after the 10 kinds of devices derived the equation D*; The fourth part is the establishment of a test system, the performance of the detector test, proposed improvements, and by experimental verification D*; PartⅤis a core part of this article, put forward the improvement of methods D*, and to design an ideal device.
