本文用傅里叶光学的观点,对任意限制孔径下虹全息成象过程中的(单色)点扩散函数及传递函数进行了系统的分析,揭示出它们与限制孔径的本质联系,建立起与一般光学成象系统可以类比的统一理论,为极限分辨率和截止频率的计算提供了形式简单、意义明确的数学依据。Based on the viewpoint of Fourier optics, we have analysed systematically the (monochromatic) point spread function and transfer function of rainbow holographic imaging limited by an arbitrary aperture, revealed the essential relation between the function and the aperture, then established a unified theory which is analogous to that of conventional imaging system. Thus we provided a simple and clear mathematical basis for calculation of the limited resolution and the cut-off frequency.
