incident point meaning in English
投射点
Examples
- 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
