Problems solved by technology
Although the first method and the second method eliminate the need for mechanical moving parts, due to the need for multiple lenses, the volume, cost and control difficulty are still very large
Although the third method only needs a single liquid lens, it requires multiple drive units, which is more complicated in structure and control

The invention discloses a single-drive liquid zoom lens, a manufacturing method thereof, and a zoom imaging method, which belong to the field of optical imaging. The single-drive liquid zoom lens uses a dielectric elastomer material to make a frustum-shaped dielectric elastomer film, injects liquid into the film, and coats the inner and outer flexible electrodes evenly on the inner and outer surfaces of the film, and the two ends of the outer and outer flexible electrodes When a voltage is applied, the film is driven to deform, thereby changing the radius of curvature of the liquid and changing the focal length of the liquid lens. Since the top of the film is fixed on a fixed transparent plate, the bottom of the film will move to compensate for the focal point movement caused by the change of the focal length of the liquid lens. , which uses a single driver to achieve a wide range and high-speed zoom of a single liquid lens. The invention also discloses a single-drive liquid zoom lens manufacturing method and a zoom imaging method based on the single-drive liquid zoom lens. The invention also has the advantages of high focusing efficiency, simple structure, easy control, and low processing difficulty.
Description
technical field [0001] The invention relates to a single-drive liquid zoom lens, a manufacturing method, and a zoom imaging method, belonging to the field of optical imaging. Background technique [0002] The zoom lens can realize different magnification imaging of the target, and is widely used in various fields such as industry, medical treatment, military affairs, and life. The zoom lens includes two functional groups, one is the zoom group and the other is the compensation group. The zoom group can change the focal length and field of view of the lens to achieve different zoom-in or zoom-out imaging of the target. The compensation group is used to compensate the focus movement caused by the change of the focal length of the zoom group, so that the focus position is always on the image sensor. Because the traditional zoom lens is composed of multiple fixed lenses, the fixed lenses are driven by mechanical moving parts to complete the zoom imaging. However, this method ...
