Errors in measurement of the object illumination angle affect fringe interpretation accuracies in speckle interferometry. To measure the object illumination angle we propose a method based on the moiré effect. The technique is easy to implement and was found to yield fast and accurate measurements.
物体照明角度测量中的误差会影响散斑干涉测量中的条纹解释精度。为了测量物体照明角度，我们提出了一种基于莫尔效应的方法。该技术易于实现，并且被发现能够进行快速准确的测量。
