摘　　要：本文描述了用平行平板构成多目标空间准线的原理，给出了当平板有光学不平行度误差时，点光源经平板多次反射、折射后的象点分布轨迹及其对准线的偏差．This paper describes the principle of the space datum line obtained by a paralleled plate. When the paralleled plate is a wedged one, the paper gives not only the distribution of the image pointS via many tines of refraction and reflection inside the plate, but also the deviation compared with the datum line.
