Embodiment Construction

[0017] The utility model is described in detail below in conjunction with accompanying drawing and embodiment.

[0018] like figure 1 Shown: a dual-liquid zoom lens optical imaging system that simulates the zooming of the human eye, which includes a cylindrical tube 4, a double-liquid zoom lens upper cover 3, a double-liquid zoom lens lower cover 6, a fixed focal length lens 1, and a flat glass sheet 5, The oily insulating liquid 7 and the water-based conductive liquid 8, the upper end of the cylindrical tube 4 is airtightly connected with the double liquid zoom lens upper cover 3, the lower end of the cylindrical tube 4 is airtightly connected with the double liquid zoom lens lower cover 6, and the double liquid zoom lens upper cover 3 is airtightly connected. Open a hole at the center and seal it to embed the fixed focal length lens 1. Two small holes 2 are symmetrically arranged on the upper cover 3 of the double liquid zoom lens other than the fixed focal length lens 1. Th...

Abstract

The invention relates to a two-liquid zoom lens optical imaging system for simulating zoom of a human eye, wherein the upper and the lower ends of a cylindrical tube are respectively and airtightly connected with an upper cover and a lower cover of a two-liquid zoom lens; a fixed focus lens is airtightly embedded into the central position of the upper cover of the two-liquid zoom lens; two small holes are symmetrically arranged outside the fixed focus lens; the central position of the lower cover of the two-liquid zoom lens is airtightly connected with a flat glass sheet; the inner wall and the lower end face of the cylindrical tube as well as the outer wall of cylindrical tube, contacting with the lower cover of the two-liquid zoom lens, are coated with a hydrophobic dielectric layer; water-based conductive liquid and oiliness insulating liquid are placed in a cylindrical container; and an electrode is respectively led out from the outer wall of the cylindrical tube and the lower cover of the two-liquid zoom lens, which is in contact with the conductive liquid, external voltage is applied between the two electrodes and the liquid interface curvature radius of the two-liquid lens is changed through adjusting an external electric field so as to drive the zoom of a lens system. The two-liquid zoom lens optical imaging system provided by the invention has the advantages of small structure, convenience for implementation and fast response speed; and the conformity of the zoom ranges of the system and the human eye can be realized.

Description

technical field [0001] The invention relates to a dual-liquid zoom lens optical imaging system and imaging method that simulates the zooming of human eyes, belongs to the technical field of intraocular micro-optical imaging, and is used for eye visual function restoration. Background technique [0002] The human visual system is composed of the refractive medium of the eye and the visual nervous system, forming a complete process of optical signal propagation, photoelectric conversion and electrical signal processing, and finally the visual center combined with people's life experience for perception. However, due to various reasons, such as trauma or congenital and acquired diseases, this complete visual circuit is destroyed, making it possible to lose visual function. Of course, some of these diseases can restore visual function through treatment, but there are still some diseases that cannot be restored through medical treatment. With the interdisciplinary development of...
