Position measurement method based on linear array CCD with inverting prism 基于线阵列CCD的带转像棱镜的位置测量
One value of the coordinate was computed according to the object-to-image conjugate relationship, and the other coordinate was measured when the image was rotated 90 ° by an inverting prism. 采用转像棱镜使得像面发生90°的旋转,可以用同一个CCD测量该点的另一个坐标值。
