Abstract

The Gabor Superlens (GSL) combines light from an array of micro-telescopes to form a single composite image. This is achieved through an initial selection of micro-telescope and array parameters that satisfy a set of first order imaging conditions. Designing a GSL presents two design challenges that are not encountered in conventional (single-aperture) lens design: the array parameters couple design characteristics such as the F/# and field of view to the paraxial design, and the composite image quality can be dominated by aberration of individual elements rather than a summation of aberration contributions throughout the design. This paper begins with an assessment of the highly parameterized design space of the Gabor Superlens to clearly identify relationships between the initial selection of first order design geometry and the consequences they have on system performance. An overview of a streamlined design method follows. Increasingly sophisticated GSL designs are then investigated to demonstrate the effectiveness of using individually corrected lens groups to improve composite image quality.
