Optical design and optimization of a miniature projector with liquid lenses via modified ant colony algorithm

A new approach of optimization and optical design for a miniature projector with two liquid lenses is proposed. To get the satisfactory performance of the optics, we achieve the optimization via integrating damped least square with the modified ant colony algorithm. The results show that we achieve a successful optical design and the optimization of the miniature projector with liquid lenses, whose clear image ranges from 120 to 2500 mm.
