Abstract

This paper introduces a unified formulism to describe many of the high contrast correction methods, namely, phase conjugation, classical speckle nulling and energy minimization. This unified formalism led to the Electric Field Conjugation (EFC) algorithm where the solution found is such that minimizes the sum of the estimated electric field at a desired plane and the electric field due to the corrective elements in the system. Applying this formalism led to the conclusion that all the other methods are special cases of EFC.
