Abstract

The invention relates to a dielectric elastomer liquid lens based on transparent conductive liquid, and belongs to the field of optical imaging. According to the liquid lens, conductive liquid is adopted as a flexible electrode, a dielectric elastomer bearing the conductive liquid is adopted as a driver, and voltage is applied to the upper surface and the lower surface of the dielectric elastomer, so that the shape of the liquid is regulated and controlled, the zooming function of the liquid lens is achieved, and miniaturization of the dielectric elastomer liquid lens is achieved. According to the invention, the miniaturization of the dielectric elastomer liquid lens can be realized without additionally coating a flexible electrode in a large area. The liquid lens has the advantages of simple driving structure, large zoom range, high response speed, low cost and the like.

Description

technical field [0001] The invention relates to a dielectric elastomer liquid lens based on a transparent conductive liquid, which belongs to the field of optical imaging. Background technique [0002] The zoom lens has the ability to adjust the focal length, which can realize imaging of objects at different distances. The traditional zoom lens uses glass or plastic as the base material, and adjusts the relative position between the lenses through a mechanical movement device (motor and gear, etc.) to achieve zooming. Due to the existence of mechanical movement devices, this type of zoom lens has the disadvantages of large volume, complex structure, easy wear, and difficult registration. Unlike conventional zoom lenses, liquid lenses do not require mechanical movement to achieve the zoom function. It changes the focal length of itself by changing the refractive index of the liquid or the radius of curvature of the surface, and has the advantages of small size, fast respons...
