  1. Abstract : in this paper , a ray - optics analysis is 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
