Document Type and Number:
Japanese Patent JP5622749
Kind Code:
B2
Abstract:
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.
