Abstract: 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.
