说明探测器的使用方法,要从性能测量说起。但限于篇幅的原因,本文主要讲一下探测器的输出与电系统的配合问题。这一步处理得好坏,关系到探测器能否充分发挥效能。测量弱辐射时,要尽可能把探测器本身的信噪比(S/N)保持到大系统的最后一级。而要做到这一点,可以说是取决于前置放大部分的制法或用法。 Describe the use of detectors, to start with the performance measurement. However, due to space limitations, this article mainly talks about the output of the detector and electrical system with the problem. This step is good or bad, is related to the detector can fully play its effectiveness. When measuring weak radiation, try to keep the S / N ratio of the detector itself to the last level of the large system. To do this, it can be said that it depends on the pre-amplification part of the system or usage.
