摘要
讨论了采用４５°旋转镜加Ｋ反射镜实现多元扫描的可行性。分析表明该扫描模式虽然可以消除单独４５°旋转镜带来的像旋转问题，但只能在严格保证初始同相位、转速稳定时才能实现，且存在偏振较大的问题。
In this paper, it is discussed that mult pixel scanning is realized by 45° rotating mirror with K mirror. The characteristics of this scanning mode are analyzed. The result shows that although the imaging rotation from 45° rotating mirror is elimated, the condition must be ensured that the same phase and fixed velocity between 45° rotating mirror and K mirror. And the polarization is seriously. It is suggested that it is notable to use this mode for space remote sensors which need high polarized sensitivity.
