【摘要】 大视场光学系统由于非共轴、视场、焦距等因素的影响,光学设计比较复杂,光学系统的畸变比较大。针对这一问题,本文给出了一种准确、实用且易于实现的畸变曲线拟合方法,并提供了相应的计算机算法。该方法也为其它复杂光学系统的畸变校正提供了一种新思路。更多还原

【Abstract】 Optical systems with large FOV are usually complex in design and have large distortion due to such factors as eccentric, field of view, and focal length. Curved-fitting of distortion, a method for distortion correcting, is presented, which is exact, practical and also easy to be realized. The corresponding algorithm for computer is also provided. This method also provides a new idea for the distortion correction of other optical systems.更多还原
