图面简单说明图1,图2是说明原来原理的电路图,图3是说明本发明原理的特性图,图4是说明本发明的一个应用实例的结构剖面图。发明的详细说明本发明讲的是热电型红外探测器:热电型红外探测器以热电晶体作为探测元件,通过探测定因红外线入射而在晶体中产生的电势进行红外线的探测。这种探测器的等效噪音功率(NEP)可如下边那样求出。这里,若首先将图1a 所示的探测器热模
BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 and Fig. 2 are circuit diagrams illustrating the principle of the invention, Fig. 3 is a characteristic view for explaining the principle of the present invention, and Fig. 4 is a sectional view showing the structure of an application example of the present invention. DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a pyroelectric infrared detector: a pyroelectric infrared detector having a pyroelectric crystal as a detecting element for detecting infrared rays by detecting a potential generated in a crystal by incidence of localized infrared rays. The equivalent noise power (NEP) for this detector can be found as follows. Here, if the detector shown in FIG. 1a is first thermally modeled
