摘要：

NE Delta T is the commonly used figure-of-merit for infrared-imaging systems using focal plane arrays (FPAs). This paper discusses an intuitive approach to understanding what determines this value in the majority of MWIR and LWIR broad-band applications, namely, the available charge storage capacity of the FPA readout. This conclusion is a consequence of the negligible amount of dark current compared to photo-current for modern detector technology.
