The results indicate that flat-top beam shaping and single-circle beam shaping at the focal plane can all be realized by using three-zone annular phase pupil filters.

模拟结果表明，利用三环相位光瞳滤波器，不仅可以在焦面上实现光强的平顶分布，而且还可以得到单环衍射光束。

The results of flat-top wave beam and cosecant square wave beam, which are gained using this method, are fairly good, testifying this method is effective in beam shaping of conformal arrays.

运用此方法得到共形圆柱阵列的平顶波束和余割平方波束方向图，效果较好，证明此方法对于共形阵列是有效的。

For resonators with random disturbed phase mirror, its modes are partially coherent, and there also exists a suitable parameter to get flat top beam.

对随机微扰型位相片，输出模式是部分相干的，在合适参数下，也可得到平顶光束。
