该技术的一个突出优点是在具有背景噪声的全息测量情况下，可以消除背景噪声对全息变换结果的影响。

A particular feature of the technique is that the influence of background noise on reconstructed results can be removed while retaining the background noise in the holographic measurements.

提出利用全息透镜阵列来实现多通道分数傅里叶变换技术。

In this paper, a technology of implementation of the multichannel fractional Fourier transform (FRT) is proposed using holographic lens array.

瞄准具的核心部件是由一块无透镜傅里叶变换位相全息图和一块全息光束变换器组成的全息光学元件。

The critical part of this sight is a holographic optical elements combined with a lensless Fourier transform hologram and a holographic beam transformer.
