摘　　要：本文从理论和实验上应用4F富里叶变换透镜系统,把三维物场转换为三维象场。象的空间位置和光场振幅的变化与透镜系统的焦距以及物体距焦平面的位置有关。根据4F系统的三维变换特性,本文还讨论了该系统对三维粒子场全息记录、再现的影响。In this paper three-dimensional object field can be transformed into three-dimensional image field by the 4F Fourier lens system according to the theory and experiment. The position of the image and the amplitude variation in the optical field are associated with the focus and the distance from the object to the front focal plane of the lens system. According to the three-dimensional transformation characteristics of the system, the effect of the system on the holography measurement of the particle field is also discussed.
