摘要：
To promote the application of sampling moire method, in this study, the determination of the moire spacing in sampling moire method is studied in details. The ordinary equation for determining the sampling moire spacing is found to be inapplicable in some cases, then a new equation is derived based on the generation mechanism of sampling moire. It is found that the ordinary equation is a particular form of the new equation in a specific range. Besides, simulation tests demonstrate that the new equation has a wide application range.
