利用热释电传感器设计的一种新颖红外探测器

Design a New Kind of Infrared Sensor Using Pyroelectric Sensor

利用热释电红外传感器，设计一种新型探测器，可提高灵敏度和信噪比，增强抗干扰能力，具有实用价值．

By using a pyroelectric infrared sensor, the author of this paper invented a new kind of detector which increases the sensitivity and signal-to-noise ratio as well as the capacity of anti-interference of this kind of instrument;therefore,this new kind of detector is of practical use.
