Blind optimization for aberration correction in confocal imaging system

Abstract

The imperfection of optical devices in confocal imaging system deteriorates wavefront which results in aberration. This reduces the optical signal to noise ratio of the imaging system and the quality of the produced images. Adaptive optics composed of wavefront sensor and deformable mirror is a straightforward solution for this problem. In this paper, we described a blind optimization technique with an in-expensive electronics without using the sensor to correct the aberration in order to achieve better quality images. The correction system includes a deformable mirror with 52 actuators which are controlled by particle swarm optimization (PSO) algorithm.
