从频域抽样理论出发，研究了空间有限图象的频谱中低频分量和高频分量之间的关系，讨论了由低频分量恢复高频分量的频域外插方法应用于体全息存储的可能性，并给出了计算机模拟的结果。
Based on the theory of frequency domain sampling, the relationship between low-frequency components and high-frequency components in the spectrum of the space-limited image is studied. The possibility of applying frequency-domain extrapolation to recover the high-frequency components from low- The result of computer simulation is given.
