Abstract

Standard optical imaging systems change their focal length by mechanical movement of lenses and lens groups along the optical axes. An alternative approach is realized in nature: many biological vision systems employ sta- tionary flexible lenses enabling different lens power dependent of the surface shape. This paper presents an entirely Mathematica-based modelling and simulation of an innovative imaging system with a liquid-filled flexible lens design. Central issue is the investigation of the exact lens surface shape as a function of the internal liquid pressure. Therefore a new Mathematica package for Zerm/ce-Polynormals was realized. Zerm/ce-Polynomials allow surface data fits with an accuracy below 50 nm. Spline-Interpolation is used to parametrize Zerrafce-Coefncients over the entire pressure range ap- plicable in the exp
