载体扰动会对光电成像系统的性能产生影响。分析载体扰动的特点及产生的原因，主要分析载体角运动对光电成像系统性能的影响。在此基础上从空间分辨率、人眼观察性能以及跟踪精度3个方面分析光电成像系统对视轴稳定精度的要求，指出对于探测器限制的光电成像系统，应将积分时间内载体的角扰动控制在探测器限制的空间分辨率内，或将像移控制在一个探测单元尺寸内，对于衍射限制的光电成像系统，应将积分时间内载体的角扰动控制在衍射限制的空间分辨率内，得出了视轴稳定精度必须在满足成像系统空间分辨率的基础上，根据实际功能需求进行确定的结论。最后通过实例验证了上述结果。

The reason why the carrier disturbance produces and the effect of carrier angular momentum on the performance of the optoelectronic imaging system are analyzed. Based on the analysis, LOS stabilization accuracy that the optoelectronic imaging system requires is also analyzed from three aspects of spatial resolution, human visual observation performance and tracking accuracy. It is pointed out that different LOS stabilization accuracy needs match different imaging system and applied situation. The conclusion shows that LOS stabilization accuracy must be determined by the system spatial resolution according to the practical function. The conclusion is verified by an example.
