同轴全息三维透明物体的计算机重构
Computer Reconstruction of the 3-D Transparent Object of Coaxial Holography
【摘要】 计算机制全息图(CGH)是通过数值计算方法生成全息图.论文将CGH技术与数字全息再现技术相结合,直接用计算机产生理想透明物体的同轴菲涅耳(Fresnel)全息图,来研究全息图的数字再现.通过对全息图进行逐层再现,并利用数字相移术消除虚像和零级像,得到了理想透明物体各层面的再现结果.
【Abstract】 Computer Generated Hologram(CGH)is generated through the method of numerical computing.Combined CGH with digital holography,the coaxial Fresnel CGH of an ideal transparent object is generated.By using digital phase-shifting method,Zero-order diffraction images and twin images are eliminated.The results of numerical reconstruction of different sections are presented.
