英文摘要：
fractional Fourier transform; hard-edged aperture; several kinds of light beams; beam characteristics; propagation
结论摘要：
首先针对强激光系统中存在噪声现状，提出了将分数付立叶变换用于空间滤波，以改善光束质量。进一步，针对带圆孔、环孔、方孔、椭圆孔的复杂光学系统现状，提出了各自的高效近似光阑模型，研究了多类特征光束（平顶光束、厄米-高斯光束、厄米正弦类高斯光束等）通过带圆孔、环孔、方孔或椭圆孔的复杂光学系统或分数付立叶变换系统的传输特征，得到了相应传输解析式，从本质上大大提高了计算效率，克服了传统衍射积分计算耗时的缺陷。同时，详细地研究了多类特征光束通过带像差的分数付立叶变换系统的传输特征，研究了分数付立叶变换或分数汉克尔变换和失调衍射光学系统的本质关联，研究了受光阑约束光束的相对相移的传输特性，研究了受限光学系统的维格纳分布函数，研究了截取光束的广义光束传输因子，研究了截取光束的Kurtosis参数，提出了一类新型空心光束模型并研究了其传输特性，开展了基于分数付立叶变换或分数子波变换的图像编解码技术的研究等。该研究工作已在Opt.Exp.、J.Opt.Soc.Am.A、Appl.Opt.、Opt.Comm.、J.Mod.Opt.等国际性光学杂志上发表SCI论文五十三篇，并已被他人SCI论文引用二十余次。
