    • Aspects of the present invention provide dynamic focusing systems and dynamic zoom systems having no moving parts. The dynamic focusing systems can include an electro-active lens, a fixed focus lens in optical communication with the electro-active lens and a focal plane. The dynamic zoom systems can include a first electro-active lens, a second electro-active lens, a fixed focus lens, and a focal plane. The electro-active lenses of the present invention can have an adjustable optical power to provide variable focusing capability. The dynamic focusing systems and dynamic zoom systems can include a controller for altering the adjustable optical powers of the electro-active lenses. The dynamic focusing systems can focus on objects at various distances based on the controlled optical power of the included electro-active lenses. The dynamic zoom systems can provide magnification and de-magnification based on the controlled optical power of the included electro-active lenses.
    • 本发明的方面提供了没有移动部件的动态聚焦系统和动态变焦系统。 动态聚焦系统可以包括电动式透镜,与电动式透镜光学通信的固定焦距透镜和焦平面。 动态变焦系统可以包括第一电动透镜,第二电动透镜,固定焦距透镜和焦平面。 本发明的电动透镜可以具有可调节的光焦度以提供可变的聚焦能力。 动态聚焦系统和动态变焦系统可以包括用于改变电活动透镜的可调光功率的控制器。 动态聚焦系统可以基于所包含的电动式有源透镜的受控光学功率,将焦点集中在各种距离的物体上。 动态变焦系统可以基于所包含的电动式有源透镜的受控光学功率来提供放大倍率和放大率。
