Optical alignment algorithm using Hadamard transformation

Abstract

In this paper, we propose a new optical alignment system using Hadamard transformation that is designed for aligning multiple channel optical components. A conventional optical alignment system assumes that the whole channels of the components are perfectly aligned with two detectors, which are placed at the end of the outermost channels of the components, indicate the maximum optical power. The proposed system is able to give us the optical power information of each channel with using one detector. The proposed optical alignment system can make up for the drawback of the conventional optical alignment system.
