A kind of coding method of gray-scale phase-only matched filter according to the phase modulation property of the spatial light modulator has presented.
根据空间光调制器的相位调制作用，提出了一种灰阶纯位相匹配滤波器编码方法。
Computer simulations show that this kind of filter is much more sensitive as compared to a matched spatial filter or a phase-only one.
计算机模拟的结果表明，这种滤波法对输入信号的旋转变化和尺度缩放变化，相对于传统的匹配滤波法及仅相位滤波法要敏感得多。
