A method of synthesizing computer-generated holograms of real existing objects is proposed that is based on a series of projection images of an incoherently illuminated object recorded from different perspectives. In accordance with the principles of computer tomography, the three-dimensional Fourier spectrum of the object is calculated by use of several projection images. A method of calculating a Fresnel hologram from the three-dimensional Fourier spectrum is proposed. Experimental results in the form of a computer simulation and optical reconstruction are presented.
提出了一种合成真实存在物体的计算机生成全息图的方法，该方法基于从不同视角记录的非相干照明物体的一系列投影图像。根据计算机断层扫描原理，利用多个投影图像计算物体的三维傅里叶频谱。提出了一种从三维傅里叶频谱计算菲涅耳全息图的方法。给出了计算机模拟和光学重建形式的实验结果。
