The main works include: In this thesis, we use Finite Difference Time Domain method to study the relationship between diffraction efficiency, angular dispersion and grating constant, to discuss how the grating figure influence the diffraction efficiency, and to research the frequency spectrum characteristic.

主要工作包括：本文分别在垂直入射和自准直入射（光垂直于光栅刻槽面入射）情况下，采用时域有限差分方法，利用商业数值计算软件OptiFDTD对二维闪耀光栅进行了矢量电磁场数值计算，研究了光栅的衍射效率和角色散随光栅常数的变化情况，研究了光栅形状对光栅衍射效率的影响，还讨论了各种光栅的频谱特性。

Because of wide spectrum bandwidth of the mode-locked laser, When the AOD works, the light spot of the 1 st diffraction order will be distorted by significant angular dispersion, thus reduces the spatial resolution of the image.

研究表明：由于飞秒激光在锁模情况下具有较宽的光谱带宽，经过AOD后的一级衍射光斑带有严重的角色散，导致光斑形状发生畸变，影响成像的空间分辨率。

The method of moments in conjunction with the asymptotic waveform evaluation technique is applied to predict the mono-static RCS of an arbitrarily shaped two-dimensional cylinder in both frequency and angular domains.
