This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.

Three important conclusions are achieved: 1 By analyzing the demand for spatial resolution of recording medium in different digital holographic recording setups, it shows that lensless Fourier transform holography can relax the requirement of spatial resolution and use the full spatial bandwidth of the CCD sensor. 2 Because of the differences of spatial resolution of image planes in different directions, reconstructed images can be relatively extended in the direction of high spatial resolution and reduced in the direction of the low one. 3 Lateral resolution of the reconstructed images is mainly determined by the highest spatial frequency of digital holograms recorded by CCD, and increases with the larger CCD size, the higher spatial resolution of the CCD sensor, and the shorter recording distance.
通过分析几种不同数字全息记录光路对记录介质空间分辨率的要求表明，无透镜傅里叶变换全息光路对CCD的空间分辨率要求最低，最能充分利用CCD的带宽；再现像面的空间分辨率在不同方向上的不一致，会导致再现像在空间分辨率高的方向上相对展宽，而在空间分辨率低的方向上相对压缩；再现像的横向分辨率主要由CCD所能记录的物体的最高空间频率决定，它随CCD的尺寸和空间分辨率的提高及记录距离D的减小而提高。
