说明:  在理想情况下采用非可靠度导向的顺序扫描法或菱形算法等相位展开的基本方法可以正确展开相位,这些算法具有最简单的和确定的扫描路径,如果测量过程中噪音较大或本身有些地方不满足采样定理,采用非可靠度导向方法展开会出现错误。可靠度导向的相位展开方法可以绕开二维相位场中的无效点,在某 种程度上将误差降到最小。
(In ideal circumstances the use of non-reliability-oriented sequence scanning method or the diamond phase unwrapping algorithm, such as the basic method can be correct to start phase, these algorithms with the most simple and determine the scanning path, if the measurement process itself and some noisy or place sampling theorem are not satisfied with, the use of non-reliability-oriented methods of error. Reliability-oriented phase unwrapping method can bypass the two-dimensional phase field invalid point, in a way to minimize error.)
