稳像光学系统设计

DESIGN OF IMAGE STABILIZING OPTICAL SYSTEM

重点沦述光学稳像的光学原理,并引用具体的平面反射镜作为光学补偿元件(也就是光稳元件)的稳像方式加以阐述,由此导出倒像系统和正像系统达到相对稳像和绝对隐像时补偿角与扰动角之间的关系式。论述采用会聚光路稳像时由棱镜的微量转动而达到绝对稳像时棱镜转动中心的求法。论述光稳元件兼作转像棱镜时光稳元件的有效孔径与转功中心和棱镜位置的关系。

The optical principle of optical image stabilization is described, and an image stabilizing method of using a plane reflector as an optical compensating element is expounded. The relations between the compensation angle and the disturbing angle for relative and absolute image stabilization are derived. The paper describes the calculation of prism rotational center when an absolute image stabilization is performed due to the slight rotation of prism by using a convergent path for image stabilization and the relationship between the effective aperture or optical stable element and the prism rotational centre and position by taking an optical stable element as an image-rotational prism.
