Liquid double lens set construction method based on micro fluidic chip

Abstract

The invention discloses a liquid double lens set construction method based on a micro fluidic chip, relating to the optical device technology field and solving the problem that the regulation range of the prior art is small. The liquid double lens set construction method comprises steps of choosing two fluids which have two different refractive indexes and are not dissolved with each other, enabling the two fluids to pass through one lens cavity in a laminar flow, enabling the two fluids to form a three-layer structure, in which a high refractive fluid is clamped between two low refractive fluids in the cavity of the lens and enabling the three-layer structure to commonly constitute a lens assembly. The invention can control the curvature of the interface of the high refractive fluid and the low refractive fluid through controlling the speed rate of the two fluids and enables the lens assembly to take on the working form. The method disclosed by the invention can perform convergence, collimation and divergence continuous adjustment.

Description

technical field [0001] The invention relates to the technology of optical devices, in particular to a method for constructing a liquid double lens group based on a microfluidic chip. Background technique [0002] Zoom lenses are key components in optical systems such as mobile phone camera lenses, microscopes, cameras, and medical endoscopes. Traditional zoom lenses are generally mechanically driven by motors, and the zoom function is realized by changing the distance between the lenses. However, most of these zoom devices are expensive, slow in zoom speed, and difficult to miniaturize, so they cannot be applied in micro-nano optics and biology. field of study. [0003] In order to overcome the above defects, some literatures have proposed a liquid single lens based on a microfluidic chip. This liquid single lens is injected with liquid in the lens cavity, and the liquid is used to realize the function of the lens, and the shape of the droplet can be changed by applying an ...
