Embodiment 1

[0045] figure 2 A schematic structural diagram of a triplet liquid lens in an initial state provided for an embodiment of the present invention, as shown in figure 2 As shown, the triple cemented liquid lens includes a hard substrate lens 1, a side wall 2, and an elastic film lens 3. The side wall 2 is connected with the hard substrate lens 1 to form a chamber 4. After the chamber 4 is filled with liquid, The filled liquid forms the liquid chamber lens. After the elastic thin film lens 3 is connected to the side wall 2, a triple cemented liquid lens which is sequentially connected by the elastic thin film lens 3, the liquid chamber lens and the hard substrate lens 1 can be obtained. Among them, the connection can be performed by optical glue. In this embodiment, the initial state of the triplet liquid lens refers to the state where the elastic film lens 3 of the triplet liquid lens is not deformed by external force. The triplet lens has the characteristics of small aberra...

Embodiment 2

[0058] Based on the first embodiment, the second embodiment provides an imaging module, and the imaging effect of the imaging module is changed by dynamically adjusting the triplet liquid lens provided in the first embodiment. The imaging module includes: a receiver 5, a processor 6, a driving motor 7, a focusing lens 8 and the triplet liquid lens provided in the first embodiment.

Abstract

The invention provides a triple-gluing liquid lens, an imaging module and a zooming method of the imaging module, and the liquid lens comprises an elastic film lens, a side wall, and a hard substrate lens. The side wall is connected with the hard substrate lens to form a cavity; the cavity is filled with liquid to form a liquid cavity lens; the elastic thin film lens is connected with the side wall to form a triple-gluing liquid lens in which the elastic thin film lens, the liquid cavity lens and the hard substrate lens are sequentially connected, and the edge thickness of the elastic thin film lens is different from the center thickness of the elastic thin film lens. Therefore, when the triplet liquid lens is in an initial state without being subjected to driving force, the aberration can be effectively improved through the triplet liquid lens; when the triple-cemented liquid lens is subjected to driving force, the overall focal length of the triple-cemented liquid lens can be dynamically adjusted by changing the curvature radius of the elastic film lens and the curvature radius of the liquid cavity lens, and therefore the zooming effect is achieved.

Description

technical field [0001] The present application relates to the technical field of optical imaging, and in particular to a triplet liquid lens, an imaging module and a zooming method for the imaging module. Background technique [0002] For the imaging quality of optoelectronic products such as mobile phone cameras and digital cameras, these optoelectronic products will use imaging modules with multiple lenses, and the zoom effect of the imaging modules will be realized through these lenses to improve the imaging quality. The requirements for the portability and convenience of optoelectronic products are getting higher and higher, and these optoelectronic products are becoming more and more miniaturized and integrated. Correspondingly, the imaging modules in these optoelectronic products are required not only to have high imaging quality, but also to And the volume should be small and the quality should be light. [0003] In order to meet the above requirements, the imaging m...
