从基本的热分析入手,导出单片热释电列阵的热传递函数,简单地分析了灵敏元的面积、调制频率和热释电电流的关系;对热释电探测器的热串音进行了分析并给出一些实验结果。
Starting with the basic thermal analysis, the heat transfer function of the single pyroelectric array is deduced. The relationship between the area of the sensitive element, the modulation frequency and the pyroelectric current is simply analyzed. The thermal crosstalk of the pyroelectric detector Analyzed and given some experimental results.
