莫尔条纹是由LCD、菲涅尔透镜和微结构透镜等周期性结构的层叠引起的,对于设计高质量的LCD背投影屏幕至关重要。为了抑制莫尔条纹,我们基于频谱分析,探讨了相关光学组件的周期结构。通过调整屏幕结构,图像上的周期性条纹可减到最小,从而得到无莫尔条纹的屏幕。
Moiré fringes are caused by the lamination of periodic structures such as LCDs, Fresnel lenses, and microstructured lenses, and are crucial to the design of high quality LCD rear projection screens. In order to suppress the moire fringes, we discuss the periodic structure of the related optical components based on spectrum analysis. By adjusting the screen structure, the periodic stripes on the image can be minimized, resulting in a screen without moiré.
