Bio-inspired variable imaging system simplified to the essentials: Modelling accommodation and gaze movement

Förster, Erik; Stürmer, Moritz; Wallrabe, Ulrike; Korvink, Jan G.; Brunner, Robert

Abstract:
A combination of an aspherical hybrid diffractive-refractive lens with a flexible fluidic membrane lens allows the implementation of a light sensitive and wide-aperture optical system with variable focus. This approach is comparable to the vertebrate eye in air, in which the cornea offers a strong optical power and the flexible crystalline lens is used for accommodation. Also following the natural model of the human eye, the decay of image quality with increasing field position is compensated, in the optical system presented here, by successively addressing different tilting angles which mimics saccadic eye-movements. The optical design and the instrumental implementation are presented and discussed, and the working principle is demonstrated.
