摘要
变焦镜头在校正像差的同时,还要求像面稳定,才能保证成像质量。采用机械补偿的方法,可以保证凸轮的准确性以使像面稳定,从而保证成像质量。首先应用动态光学理论推导出变焦光学系统的像移补偿组公式,从而得到像移补偿组的轨迹曲线。再根据推导得出的补偿曲线加工出凸轮机构,可对光学系统变焦带来的像移实现完全补偿。此外还给出三个变焦系统的设计实例,用来验证该方法的正确性和实用性。
To ensure the imaging quality of the zoom lens, the image plane stabilization should be maintained, while the aberration is corrected. Mechanical compensation can ensure the accuracy of the cam, accomplish the image plane stabilization and keep the imaging quality. With dynamic optical theory, the image motion compensating group formula of the zoom optical system is derived, and the trace curve of the image motion compensating group is plotted. With the plotted curve the cam is fabricated, and compensates the image motion caused by the zoom of the optical system totally. The design for three zoom systems is presented, Which validates the validity and the practicability.
