abstract = "A f-theta laser scanning optical system with wide scanning angle, high resolution and compactness is proposed. Specifications of the system are analyzed and calculated. To simplify the optical layout and improve the optical performance, freeform surfaces are used to describe the shape of the lens. The method about how to create a user-defined surface in the optical design software is introduced. The optimization strategy and implementation method of freeform surface are mentioned. The design result achieves a f-theta laser scanning optical system with a field-of-view of ±55.6°, a resolution higher than 600 dots per inch, and a total length less than 150mm. The modulation transfer function of the system is close to the diffraction limit and the linear distortion is less than 3μm.",
