摘　　要：通过性状较为一致的(Pb_1-x_Sr_x)TiO_3(简称PST)红外敏感元电容器对的制备,将其设置在电脉冲读出电路中,通过脉冲电压的调制,可读出其温差下的介电响应特性,从而得到红外辐射的信息。测试表明,随着辐射强度的增强,电路中净充放电电荷值平缓地增加。表明用这种方法进行红外辐射的探测是可行的,其探测电路结构简单紧凑,且易作成阵列器件。通过进一步改进性能,可望发展出新一代IR探测器件。The （Pb1-xSrx）TiO3 capacitor couples with similar property and structure were fabricated. The capacitor couples were used in the electrical couple-impulses circuit to detect the IR information through the measurement of their dielectric temperature response, Experiment result indicated that the net charges of the circuit increased with the IR intensity smoothly, which showed that it was feasible for IR detecting by this method. It was possible for this device to be exploited to a new generation IR detector with an excellent structure and property.
