Abstract

The invention relates to a rapid varifocal device based on double liquid lenses. The rapid varifocal device comprises a lens cone, a light extinction cover and a manual liquid lens electric control device, wherein the lens cone is formed by the two liquid lenses and a plurality of fixed lenses, the light extinction cover is fixed to the lens cone, an imaging device is installed at the tail end of the light extinction cover, and electric control over the manual lenses is achieved through the manual liquid lens electric control device. The focal lengths of the two liquid lenses can be changed by changing voltages applied to the electric liquid lenses and the angles of a manual liquid lens rotating device, and therefore the varifocal function of the whole rapid varifocal device is achieved.

Description

technical field [0001] The invention relates to a fast variable focal length device based on a double liquid lens. Background technique [0002] Variable focal length optical system plays an important role in various imaging systems, and the change of focal length can be realized by moving the lens, changing the refractive index or changing the shape of the lens. In recent years, variable focal length optical systems have been more and more widely used in imaging systems in aerospace and military fields because of their fast and continuous target detection and flexible and convenient image motion compensation capabilities. At present, zoom technology can be divided into traditional zoom and new zoom according to the lens movement mode. The traditional zoom optical system usually consists of several groups of lens components with fixed focal length. The zooming process is to change the relative position of the fixed focal length lens group through a mechanical device such as...
