Liquid zoom lens with human-like lens adjustment and its aberration correction method

Abstract

The invention discloses a human-eye-crystalline-lens adjustment imitating liquid zoom lens and an aberration correction method of the human-eye-crystalline-lens adjustment imitating liquid zoom lens. A first circular ring is installed between a first round transparent film and a second round transparent film to form a plus lens containing cavity, a second circular ring is installed between the second round transparent film and a third round transparent film to form a minus lens containing cavity, a rodless cavity of a first plunger device is communicated with the plus lens containing cavity through a first hose, a rodless cavity of a second plunger device is communicated with the minus lens containing cavity through a second hose, and the two containing cavities are both filled with transparent liquid to form a plus lens and a minus lens. According to the human-eye-crystalline-lens adjustment imitating liquid zoom lens, continuous zooming within a design-required zoom range can be achieved, primary position chromatic aberration, primary spherical aberration and primary sinusoidal aberration can be further corrected at the same time, and therefore imaging is complete. The human-eye-crystalline-lens adjustment imitating liquid zoom lens is simple in structure, small in size, light in weight, stable in optical axis, continuous in zooming, high in response speed and accuracy, convenient to operate, easy to manufacture, low in cost and capable of being widely applied to various modern imaging systems.

Description

technical field [0001] The invention relates to a bionic machine vision device, in particular to a liquid zoom lens adjusted by imitating a human eye lens and an aberration correction method thereof. Background technique [0002] With the development of science and technology, people's demand for high-tech products, such as intelligent and automated auxiliary robots and related products, is increasing, which has become the development direction of the field of engineering science. Robot technology integrates many high technologies, and its application not only moves from the manufacturing field to the non-manufacturing field, but also continues to expand to non-industrial fields such as military, anti-riot, medical treatment, service, and entertainment at an alarming speed. For robots, vision is also an important means of perceiving the external environment. Although its development has made great progress, it still lags behind other functions, such as walking, arm and finge...
