摘　　要：分析了光学融合方法与电子融合方法的不同,对可见光的菲涅耳衍射与多层减透膜渐变衍射进行了分析、仿真和实验,在此基础上提出了在异形屏幕多通道投影中采用多层减透膜渐变衍射光学融合的方法。此方法在亮、暗场景下都可以消减通道间重叠区域的光强增加,以实现异形屏幕无缝全景图显示亮度参数的一致性。The optic blending method as oontrasted with the electronic blending method is analyzed. Fresnel diffraction of visible light and multi-filter shade diffraction is analyzed and simulated and tested. Based on these discussions, an optic blending approach by multi-filter shade diffraction is put forward to suppress an increase in a luminance of a multi-projection abnormity projection screen in an overlap area to consistency of brightness for a seamless visual image whether in high light scene or in dim scene.
