Development of adaptive fiber collimators for conformal fiber-based beam projection systems

摘要

We describe bimorph piezoelectric fiber actuators, which enable tip and tilt control in fiber collimators, as well as their integration into a fiber-array based beam-projection system. A mechanism for alignment of individual fiber actuators within the array was developed. It provides six degrees of freedom and allows for high subaperture density. The alignment procedures for a seven-subaperture prototype system as well as first results from evaluation experiments are presented.
