Title:
CATADIOPTRIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/108137
Kind Code:
A1
Abstract:
A catadioptric system (A1) and an imaging apparatus using the same according to the present invention comprise a catoptric system (A11) with a pair of reflecting surfaces for bending an optical path, and a dioptric system (A12) with a predetermined optical power, the dioptric system (A12) including an optical system movable in accordance with a predetermined function. The catadioptric system (A1) with such configuration and the imaging apparatus using the same can be suitably equipped with the optical system movable in accordance with the predetermined function. For example, when the predetermined function is a focusing function, the configuration enables the provision of a catadioptric system in which the optical system for focusing can be moved by a simpler structure, and an imaging apparatus using the same. Further, when the predetermined function is an image stabilizing function, for example, the configuration enables the provision of a catadioptric system that can be equipped with an optical system for realizing an optical system shifting-type image stabilizing function, and an imaging apparatus using the same.
