Abstract

The invention provides a super-large-zoom-range imaging system based on liquid lenses. The imaging system comprises an auxiliary lens set, the liquid lens I, the liquid lens II, the liquid lens III, a front end semi-transparent semi-reflective mirror, a rear end semi-transparent semi-reflective mirror, a front end mirror, a rear end mirror, a photographing channel liquid diaphragm, a telescopic channel liquid diaphragm and an optical imaging device. The system comprises two optical paths, can be switched to be a large-view-field photographing mode and a small-view-field telescopic mode, and accordingly achieves a super-large zoom range.

Description

technical field [0001] The invention relates to a zoom imaging system, more specifically, the invention relates to an imaging system with a super large zoom range based on a liquid lens. Background technique [0002] The zoom imaging system has gradually developed and become an indispensable optical imaging system for human beings. It plays an important role in many fields such as military affairs, entertainment, scientific research, teaching, medical treatment, and industrial production. Traditional zoom imaging systems are based on mechanical movement to change the focal length, such as SLR cameras, but mechanical movement zoom is not conducive to equipment miniaturization, and the cost is also high. Therefore, zoom systems without mechanical movement are gradually gaining attention. Among them, the zoom imaging system based on the liquid lens can realize the change of the focal length by using the change of the voltage, therefore, the miniaturization and weight reduction...
