二元光学波面变形器件的研究
Binary Optical Element for Laser Beam Shaping
摘要
基于计算全息原理设计了二元光学波面变形器件,一块二元光学器件的衍射效率比计算全息可提高4倍,高斯波面整形需要二块整形光学器件,二元光学器件的激光利用率比计算全息提高16倍,而且制做工艺简单.
Abstract
A binary optical element is designed based on computer generated hologram for shaping the profile of laser beam from Gaussian to top-hat. As it is a binary optics, so the diffraction efficiency is four times than the holographic one's. The approach is easy in fabrication. The design and experimental results are presented.
