Light path selector based on double liquid lens and realization method thereof

Abstract

The invention discloses a light path selector based on a double liquid lens. The light path selector comprises the double liquid lens, and a transmitting end and a receiving end which are arranged at the two sides of the double liquid lens. The invention also discloses a realization method of the light path selector based on the double liquid lens. A double liquid lens model is established by adopting optical design software, and ray tracing is performed on the double liquid lens so that the convergence situation of beams is obtained; and the position of a receiver is determined according to the acquired convergence situation of the beams and the requirement for the size of convergence light spots. Voltage between all the tube walls and electrodes of conductive liquid is appropriately changed according to the requirements so that the optical axis is enabled to rotate a specific angle. The liquid lens system model is established by adopting the optical design software, such as Zemax, and ray tracing is performed on the double liquid lens system so that the position of the receiver is designed. The light path selector based on the double liquid lens is simple in structure, convenient to operate and low in cost so that an adjustable and visual model is provided for realization of the light path selector based on the double liquid lens variable optical axis technology.

Description

technical field [0001] The invention relates to the field of micro-optical imaging technology, in particular to an optical path selector based on a double-liquid lens and a realization method thereof. Background technique [0002] In 2000, French BrunoBerge and other researchers proposed the prototype of electrowetting "bulk structure" variable focus optical lens based on Gorman's design. It covered the transparent electrode with an edge film to form a sandwich structure, and proposed a positioning water droplet center. method, and precisely control the shape of the droplet by changing the applied voltage to achieve the purpose of zooming. In 2004, Philips Labs developed a bionic zoom microlens based on the design of the human eye. [0003] The electrowetting effect is a physical and chemical phenomenon, which changes the wettability of the droplet on the substrate by changing the voltage between the conductive droplet and the substrate, that is, changing the contact angle ...

Problems solved by technology

[0004] The traditional optical path selector is usually composed of multiple optical elements, and the optical path selection is realized by adjusting the mechanical device, which has the disadvantages of complex structure, high loss, and high power consumption.
