The electrowetting effect is one physical chemistry phenomenon, it through adds certain external voltage in the solid - liquid contact surface to change the liquid to the solid moist degree, thus changing the contact angle of liquids and solids. In this article double liquid zoom lens are based on this kind of electrowetting effect. Optics focal variation system realizes the focal variation to satisfy two basic conditions[2]: (1) changing the focal distance; (2) maintaining the image plane position invariance. The single liquid zoom lens cannot maintain the position of the image formation surface invariance, this article takes on the electrowetting effect double liquid zoom lens as a foundation, and designs to realize new optical systems without mechanical movement focal variation using the motor control, and through MATLAB software simulation inferential reasoning the result. |
