A new optimization for a continuously varying amplitude pupil filter that maximizes the signal concentration factor for a given transverse gain is derived. The filter has a simple parabolic amplitude transmittance, and is an example of a Sonine filter. The connection between different definitions of gain factor is discussed.
推导了一种用于连续变化幅度光瞳滤波器的新优化方法，该方法能在给定横向增益的情况下使信号集中因子最大化。该滤波器具有简单的抛物线幅度透过率，是索宁滤波器的一个示例。讨论了增益因子不同定义之间的联系。
