红外探测器是各种红外整机的关键部件,它的输出噪声的大小直接影响着整机的灵敏度。有些探测器在单独测试时,输出噪声并不高,但当它与整机联试时输出噪声有时高出数十倍,数百倍,甚至大到可以淹没信号的程度,以至整个装置无法工作。作者认为,整机上各种频率的机械振动和电磁场的干扰是引起探测器噪声增加的两个主要原因,而改变探测器
Infrared detector is a key component of a variety of infrared machine, its output noise directly affects the size of the overall sensitivity. Some detectors do not produce high output noise when tested individually, but output noise can sometimes be as much as tens, hundreds, or even as large as a signal that can submerge the unit so that the entire device does not work . The author believes that the machine on various frequencies of mechanical vibration and electromagnetic interference is the cause of the detector noise increases two main reasons, and change the detector
