引起多元探测器串音的原因很多,例如PN结型器件少数载流子具有一定的扩散长度、探测器结构设计上有问题、多元探测器之间有漏电阻等。归结起来可以分成光学串音和电学串音两类,比较而言,后者更主要。目前,我们用Hg扩散成结法制作的HgCdTe探测器的电学串音有时较为明显,除上述诸因素外,还有可能是PN结区较深,引起相互串通。对由于各探测元之间的漏电阻而引起 Crosstalk caused by multiple detectors for many reasons, such as PN junction device minority carriers have a certain diffusion length, the detector structure design problems, leakage resistance between multiple detectors and so on. To sum up can be divided into optical crosstalk and electrical crosstalk two types, in comparison, the latter is more important. At present, the electrical crosstalk of the HgCdTe detector that we use to diffuse Hg into the method of fabrication is sometimes obvious. In addition to the above factors, it is also possible that the PN junction area is deep and leads to mutual collusion. Due to the leakage resistance between each probe caused
