The critical part of this sight is a holographic optical elements combined with a lensless Fouriertransform hologram and a holographic beam transformer.
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 OTF (Optical Transfer Function) of an optical system can be evaluated by the FourierTransform of the first derivative of the optical image of an knife-edge (object).
对光学系统输出刀口像的一阶导数做傅里叶变换,可以得到该系统的光学传递函数(OTF)。

Neither the coherent optical input image nor the Fouriertransform hologram of the reference image is required by this system.
