"Liquid lens" technologies promise significant advancements in machine vision and optical Communications systems. Utilizing two isodensity liquids with differing electrical characteristics to focus, liquid lenses require no moving parts for operation. Liquid lenses also offer Iower power consumption and smaller package sizes than their electromechonical counterparts. Liquid lenses are quickly becoming a viable alternative to conventional lens technologies for a wide variety of applications. Notable variations of liquid lens technology are discussed. A machine vision student project utilizing this technology will be discussed in detail. An adaptotion of the machine vision project for use in human vision correction, and independent research in optical Communications are also used to exemplify the versatile nature of this technology.
