In dynamic measurement field, when using digital speckle pattern interferometry, we always deal phase with time-average method and spatial carrier phase-shifting method.

在动态测试领域中，数字散斑干涉技术常用到的相位处理方法有时间平均法和空间载波相移法。

The present method is achieved with an amplitude gray-scale spatial light modulator (SLM) as the image input device and based on double exposure holographic phase-shifting interferometry.

像元结构对输入图像的抽样使联合变换功率谱和相关输出是空间周期性重复的。
