全息图数字再现中零级衍射斑的消除
摘要
分析了无透镜傅里叶变换全息图数字再现时零级衍射斑对再现像的影响,提出了用全息数字相减及数字重现来消除零级斑实现无零级数字全息再现的方法,给出了计算机模拟实验结果,并对再现结果作了分析。
Abstract
The effects of zero-order diffraction spot on the reconstruction images in the digital reconstruction of lensless Fourier transform hologram are analyzed.A method to eliminate the zero-order diffraction spot with digital subtraction and digital reconstruction of hologram is suggested. Reconstructions of hologram without zero-order diffraction spot are implemented successfully. The results are discussed.
