Tunable anamorphotic imaging system based on fluidic cylindrical lenses

Abstract

We present an anamorphotic imaging system with a separately tunable magnification in horizontal and vertical direction in order to change the aspect ratio of the image. The design is based on cylindrical membrane lenses made of aluminum nitride with tunable focal power to realize a vario system without moving elements. We demonstrate the design concept of cylindrical lenses with a very compact geometry, the optical system as well as experimental results.
