A Design of an Optical System of Liquid Filled Lens which can Adjust the Focus

Abstract:

The configuration of the system combines a liquid-filled lens, a flexible sensor membrane and a self-adjusted optical compensation device. We focus on optical compensation between the liquid-filled lens and the sensor membrane to make the system has good optical characters. For a single lens optical system, the curvy sensor membrane has better performance than flat type sensor in both the image quality of MTF, aberration and angle of view. To prove the idea, an optical measure system is developed and the optical system is also made. The experimental results show that this system do has a better performance in optical character.
