    • Zoom lens systems and methods for imaging incoming rays over a range of ray angles are disclosed. The incoming rays are characterized by at least phase. The zoom lens system includes an optical axis and is characterized by a plurality of modulation transfer functions (MTFs) corresponding at least to the range of ray angles. The zoom lens system includes an optical group disposed along the optical axis, including at least one variable optical element that has a variable focal length selectable between at least two distinct focal length values. The optical group also includes a wavefront coding element. The wavefront coding element alters at least the phase of the incoming rays, such that the plurality of MTFs corresponding to the range of ray angles, for each one of the two distinct focal length values, are less sensitive to misfocus-like aberrations than a corresponding system without the wavefront coding element.
    • 公开了变焦透镜系统和用于在一定范围的光线角度下成像入射光线的方法。 入射光线至少具有相位特征。 变焦透镜系统包括光轴并且由多个至少对应于光线角度范围的调制传递函数(MTF)表征。 变焦透镜系统包括沿着光轴设置的光学组,其包括至少一个可变光学元件,该可变光学元件具有可在至少两个不同焦距值之间选择的可变焦距。 光学组还包括波前编码元件。 波前编码元件至少改变入射光线的相位,使得与两个不同焦距值中的每一个的光线角度范围相对应的多个MTF对类似散焦的像差的敏感性小于对应 系统没有波前编码元件。

    • A tunable interference add/drop filter system combines an interference filter (308) or the like with a mirror (312) attached adjacent to the filter at an angle under 180 DEG to form a reflector assembly (314). The reflector assembly is rotated to tune the filter system. The dropped output (304) passes through the filter, while the passed output (306) reflects off of the filter and the mirror. The direction of the passed output beam is a fixed angle from the input beam, and the beam is translated sideways by a fixed amount, no matter how much the reflector assembly is rotated. Thus the dropped output (or complementary output) can be retained. A null state switch (500) prevents light from reaching the filter while the filter system is tuning.
    • 可调谐干扰分插滤波器系统将干涉滤光器(308)等与在180度以下的角度邻近过滤器附近的反射镜(312)组合以形成反射器组件(314)。 旋转反射器组件以调整过滤系统。 丢弃的输出(304)通过过滤器,而通过的输出(306)反射离开过滤器和反射镜。 通过的输出光束的方向与输入光束成一个固定的角​​度,而不管反射器组件旋转多少,光束横向平移固定的量。 因此,可以保留丢弃的输出(或互补输出)。 空白状态开关(500)在过滤器系统调谐时防止光线到达过滤器。
