- W2051209498 abstract "ABSTRACT We discuss the different contributions to aberrations in the liquid crystal adaptive lens, specifically thosedue to errors in voltage settings at the electrodes (which could be dithered) and those due to quantization errors ofthe electrodes and meshing errors between electrodes (which are fixed upon device construction). For application ina large optical memory, the dominant errors are the fixed errors. Linear current meshing is introduced as a solutionto these errors because a current-carrying plate joining adjacent electrodes provides a linear interpolation of indexbetween the electrodes. 1. Introduction This paper describes the effect of phase errors on the imaging performance of the liquid crystal adaptivelens (LCAL) and introduces a technique to reduce the most prominent component. The LCAL utilizes an array ofelectrodes to electrically shape the index of refraction such that light entering the cell is brought to focus.13 Thefocal length is controlled by the curvature of the index modulation. The ideal refractive index profile is defined as" @default.
