可以用胶片、全息图和光栅作为滤波片。
本文提出采用对二个物体进行位相编码的迂回位相计算全息图对该两物体实现二重位相匹配滤波。
In this paper I have shown that the double phase-only matched filtering can be realized by a computer generated hologram of detour phase with phase coding for two objects.
该技术可应用于全息图制作、彩色图像变换、光学图像加密、滤波器的制作、光学防伪等领域。
This system can be used in hologram producing, color image transform, optical image encryption, filter producing, optical anti-counterfeiting and other fields.
