In addition to alternating phase difference between two aims of interferometer, the intensity of light of the interference fringes will vary in the same frequency, which is called as phasemodulation.
当两相干光附加一按固定频率变化的相位差时，其干涉条纹的光强将随之交变，即为相位调制干涉。

A kind of coding method of gray-scale phase-only matched filter according to the phasemodulation 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。

Steering accuracy is limited by the quantized phasemodulation values and the number of phase pixels for spatial light modulators (SLMs).
