DISPLACEMENT MEASURING SYSTEM FOR USING MICROFLUIDIC LENS AND METHOD THEREOF

摘要

A displacement measuring system using a microfluidic lens and a method thereof are provided to allow a user to adjust a voltage manually when necessary while watching a monitor, and to measure the displacement by using auto focusing of the microfluidic lens. A displacement measuring system comprises a camera device, a voltage control part(320), a monitor(330), and a sensing and processing part(312). The camera device for taking pictures of a measuring object(200), is provided with a lens(311) focusing the taken image according to a predetermined voltage. The voltage control part applies the predetermined voltage. The monitor checks the focusing state according to the predetermined voltage. The sensing and processing part calculates the distance to the object by the image focused by the camera device. The lens includes a fluidic lens having a first and second fluid and an interfacial part therebetween. The radius of curvature of the interfacial part is controlled by adjusting the voltage of the voltage control part through the monitor.
