The incoherent imaging system in its isoplanatic region is a linear light intensity system with invariance in space.
非相干成象系统在等晕区内是空间不变性的光强线性系统。

To improve the detective ability of air-borne and ground laser lidar systems, the expressions of isoplanatic angles of single-and dual-conjugate systems were deduced.
为提高机载和地面激光雷达的探测能力，导出了单、双层共轭系统等晕角计算公式。

The result will be improved if the degraded image is divided into regions to be restored according to the isoplanatic theory, on the basis of that the system is a linear variant one.
