When the target is a grey body, especially when its temperature is nearly equal to that of circumferential bodies, the target's self-radiation and the circumferential radiation reflected by the target must be considered. Thus, the sensibility equations of various infrared systems have to be modified. According to these modified equations, we can explain some experimental phenomena that-can not be interpreted by the unmodified equations in which only self-radiation is taken into account.

当目标为灰体时,尤其是目标温度与环境物体的温度相近时,必须同时考虑目标的自身辐射和它对环境辐射的反射。这样,各种红外系统的灵敏度方程就需要修正。根据这些修正后的方程,就可以解释原来只考虑自身辐射的方程所无法解释的实验现象。其中,对于热成象系统,我们作了重点讨论,不但考虑了场景中相邻单元的温差、比辐射率差和反射率差的影响,而且考虑了扫描效率、扫描重迭率、串联或并联列阵元件、加场镜或浸没透镜等的影响,得到比较完整的灵敏度方程和噪声等效温差NETD的表达式。对于NETD中的积分X_T的计算方法,我们也作了介绍并给出数值表。

This paper gives a systematic discussion on the formulae of modulate transfer functions (MTF) of infrared system (including the detector array), noise equivalent temperature difference (NETD) and minimum resolvable temperature difference (MRTD) for airborne thermal imaging system. As an example, the MTF, NETD and MRTD of a multispectral scanner are calculated. They are compared with the experimental results and proved themselves closely consistent.

本文系统地讨论了红外整机各部分调制传递函数的表达式(特别是列阵探测器的调制传递函数的表达式)以及机载热成象系统的噪声等效温差和最小可分辨温差的表达式。以上海技术物理研究所最近研制成功的多光谱扫描仪为例,在用电子计算机算出该仪器的光学系统的弥散盘之后,计算了这些系统参数,并与实验结果作了比较,二者符合得较好。
