摘　　要：应用几何光学理论研究了多光束转镜扫描场的非对称性 ,导出多光束扫描入射点位置矢量、反射线标量表达式、观察面上的扫描轨迹方程 ,并研究了扫描远场的非对称性。In this paper,a ray optics analysis is perform ed to investigate the asymmetry of dual beam scanning field produced by a rotati ng polygon.Some basic equations of dual beam scan are derived,such as,the posi tion vector for the incident point,the scalar expression for reflected ray,sca n pattern on observation plane ect.The far field asymmetry of the scanning fiel d has been discussed.
