Consideration of the principle for rectilinear scanning of a parabolic mirror in front of the objective lens |
| |
| Abstract: | To form the clear image in a wider view-field,the focus objective of the laser scanning system is either fθ lens or a parabolic mirror in front of the objective.In this paper,the imaging characters and design methods of the parabolic mirror scanning system are analyzed theoretically. |
