Abstract
In this paper,a ray-optics analysisis performed to investigate the asymmetry of dual beam scanning field produced by a rotating polygon.Some basic equations of dual beam scan are derived,such as,the position vector for the incident point,the scalar expression for reflected ray,scan pattern on observation plane ect.The far field asymmetry of the scanning field has been discussed.
