Paper Abstract

We discuss the different contributions to aberrations in the liquid crystal adaptive lens, specifically those due to errors in voltage settings at the electrodes (which could be dithered) and those due to quantization errors of the electrodes and meshing errors between electrodes (which are fixed upon device construction). For application in a large optical memory, the dominant errors are the fixed errors. Linear current meshing is introduced as a solution to these errors because a current-carrying plate joining adjacent electrodes provides a linear interpolation of index between the electrodes.
