ABSTRACT:This paper explains two iterative phase recovery methods where the goal of each one is different. The Phase Diversity method is used to recover the wavefront aberrations in optical incoherent imaging systems when an extended object is illuminated. The purpose of the Multi-plane Phase Retrieval method is recovering the object complex field seen from the image plane, therefore the object has to be illuminated with coherent light. Both methods are simultaneously used to pick out the aberrations and free aberrations object phase. The use of both methods is proposed as a methodology for the integration of optical instruments.Key words: phase retrieval methods, optical aberrations.
RESUMEN:Este artículo explica dos métodos iterativos para la recuperación de la fase, donde el objetivo de cada método es diferente. El método de Diversidad de Fase se usa para recuperar las aberraciones ópticas de un sistema formador de imagen usando iluminación incoherente y un objeto extendido. El propósito del método Multi-plano Iterativo de Recuperación de Fase es recuperar el campo complejo del objeto y por tanto la iluminación debe ser coherente. Ambos métodos se usan simultáneamente para obtener tanto las aberraciones como la fase del objeto libre de aberraciones. El uso de ambos métodos se propone como una metodología para la integración de instrumentos ópticos.
