摘　　要：本文提出了一种新型组合转镜式多方位扫描条码识别器光学设计原理及其光路，扫描轨迹以及必要的公式。实验样机表明它能对工作距离１ｍ，景深０．４ｍ，工作范围０．４０．The principle of the design of a new kind of combined polygon scanner for bar code is proposed. Prototype of this machine was manufactured and gave good results that it could satisfy the effective scanning for a moving bar code at lm/s within a cubic space of 0 35m×0 35m×0 35m, the work distance of lm.
