摘　　要：为了表征狭缝光栅自由立体显示器存在的左右眼视差图像的混叠程度,提出了立体图像串扰度C的概念。根据狭缝光栅自由立体显示器的结构和工作原理,应用几何光学知识,分析得出了立体图像串扰度C的计算公式,并给出了一个具体的狭缝光栅自由立体显示器的计算结果。通过观看实验,证明了所定义的立体图像串扰度C可以定量描述观看者在立体可视区域看到的立体图像的串扰程度。The stereoscopic image crosstalk may decrease the quality of presented stereoscopic images.The concept of stereoscopic image crosstalk factor C is defined to indicate the degree of crosstalk between the left and right parallax images.According to the structure and principle of the autostereoscopic displays,the calculation formulas of stereoscopic image crosstalk factor C are obtained using geometry principle.The simulated results of an autostereoscopic display device show that the concept of stereoscopic image crosstalk C can quantificationally describe the degree of crosstalk for stereoscopic images seen by viewers in the stereo viewing zone of the display.
