A Study of Optical Design of Miniature Zoom Optics with Liquid Lenses
A new optical design of 2X miniature zoom optics with liquid lens elements are proposed in this research.Liquid lenses are optical components especially designed to vary optical power focusing in small form factor imaging systems.They can either be used as an add-on on a stand alone fixed focus lens module to convert it into an auto-focus module; or be integrated within the auto-focus lens module at design stage.Besides,liquid lens could be as a vari-focal component,which takes advantage of reduce the size of the optical zoom lens.In this research,two liquid lenses are employed in this research in order to minimize the overall length of miniature zoom optics.Compared with complexity of conventional zoom method with complicated mechanical cam system,new proposed zoom optics with two liquid optics will be a great improvement because of remove of complicated opto-mechanical system required.In other words,focus,zoom and zoom compensation will be handled by electronics of liquid optics with signal from electronic chips,which might significantly minimize volumetric size of zoom optics.However,there are difficulties in optimization of zoom optics with liquid lens when employing traditional LDS method.In this paper,we propose a new method,a discrete lens group shift(DLGS),to solve this problem.This research presents some optical design with decent performance,which represents success of miniature zoom optics with liquid optics.
