本文用几何方法分析高速转镜相机的基本光学原理,证明了离轴扫描反射镜的象落在巴斯加(Pascal)蜗牛形曲线上,叙述快门动作的米勒(Miller)原理,按瑞利标准对运动模糊进行简单的评价。
This paper analyzes the basic optical principle of a high-speed rotary mirror camera by means of geometry and proves that the image of the off-axis scanning mirror falls on the Pascal snail-shaped curve and describes the Miller principle of the shutter action, The standard makes a simple assessment of motion blur.
