摘　　要：为了提高莫尔条纹动画的成像质量,文中基于莫尔条纹动画形成原理,建立了莫尔条纹动画的数学模型,针对光栅参数对莫尔条纹动画像质的影响因素,制作了动画底图。基于Matlab程序实现莫尔条纹动画的快速批量制作,通过数值模拟对不同光栅参数下的莫尔条纹动画的像质进行了分析。研究结果表明:莫尔条纹动画底图中包含的总信息量与动画的帧数和光栅参数无关;当光栅的占空比为1∶7时,莫尔条纹动画视觉上的空间和时间连贯性最好。该研究对于高质量莫尔条纹动画的制作提供了重要参考。To improve the imaging quality of moiréfringe animation,the paper describes the formation principle of moiréfringe animation systematically,with its mathematical model established.The production of moiréfringe animation with Matlab is studied and the image quality is analyzed by numerical simulation.The results indicate that the total amount of the information contained in the moiréanimation film is independent of the number of frames and the grating parameters.The moiréfringe animation with the best visual quality can be obtained when the duty ratio of the grating is 1∶7 pixels.This study provides a significant reference for the production of high-quality moiréfringe animation.
