摘要
为了研究逆向调制器结构参数及接收距离对系统反射光特性的影响,通过建立“猫眼”目标离焦结构等效模型,采用几何光学方法对该模型进行理论分析,推导出表达反射光特性(发散半角、反射光斑半径、反射光功率密度)的相应计算公式并进行数值计算和实测实验。理论分析与实验结果表明:逆向调制器结构参数及接收距离对调制系统反射光斑半径和功率密度的影响明显且呈规律变化,减小透镜焦距、增大透镜口径、增大接收距离可以加快反射功率随离焦量变化速度,有助于改善调制效果。且一般情况下,正离焦的反射光发散半角小于负离焦的反射光发散半角。
Abstract
The influence of retro-reflect modulation reflected optical characteristics on the retro-reflect modulation structure parameters and receiving distance were studied by establishing off-focus structure equivalent model of retro-reflect modulation, and the theory of retro-reflect modulation model with geometrical optics method was analyzed. Some expressions related to the structure was given, numerical calculation and experiment were completed. Results show that the retro-reflect modulation structure parameters and receiving distance affect the variations of modulation system reflection power boviously and regularly. Moreover, reducing the lens focal length, increasing the lens aperture and increasing the receiving distance can increase the rate of change, and make contribution to improve the modulation effect. And under normal circumstances, the divergence of the reflected beams is much smaller when the mirror in the focal plane moves forward out of focus.
