Adaptive lenses based on liquid crystals

摘要

This paper discusses the principles and theoretical foundations of the construction of various types of adaptive lenses based on liquid crystals. It is shown how they have evolved from lenses that operate in polarized light with long focusing times to lenses that operate in unpolarized light with increased aperture and response rate and enhanced image quality. The possibilities of using them in optical systems are discussed. (c) 2008 Optical Society of America.
