摘要	An optical delay line (200) for use with an optical source including input/output optics optically coupled to the optical source and a curved mirror (216) with a reflective surface that is centered about an evolute curve (212) of the delay line (200) to retro-reflect light traveling along a delay line beam path tangent to the edge of the evolute curve. The input/output optics direct light from the optical source along the delay line beam path (214) and direct delayed light from the delay line beam path (214) out of the optical delay line along an output beam path. The input/output optics (204) and/or the curved mirror (216) rotate about the evolute curve (212) at a selected angular speed. The reflective surface has a curvature based on a parametric curve that is calculated from the evolute curve such that the delay of the delay line (200) varies according to a predetermined function as the input/output optics and/or the curved mirror rotate.
其他摘要	一种用于光源的光学延迟线（200），包括光学耦合到光源的输入/输出光学器件和具有以延迟线（212）的渐变曲线（212）为中心的反射表面的曲面镜200）以反向反射沿着与渐变曲线的边缘相切的延迟线光束路径行进的光。输入/输出光学器件沿着延迟线光束路径（214）引导来自光源的光，并且沿着输出光束路径将来自延迟线光束路径（214）的延迟光引导出光学延迟线。输入/输出光学器件（204）和/或曲面镜（216）以选定的角速度围绕渐变曲线（212）旋转。反射表面具有基于从扩展曲线计算的参数曲线的曲率，使得当输入/输出光学器件和/或曲面反射镜旋转时，延迟线（200）的延迟根据预定函数而变化。
