It : aims to recover the unknown phase of an optical wavefront from intensity measurements. This problem arises in avariety of practical applications, including imaging, holography, and optical testing. For non-interferometric optical fields, i.e., fields that are not directly related to interference fringes, phase retrieval is achallenging task. In this study, we propose to investigate phase retrieval algorithms for non-interferometric optical fields. Our goal is to develop efficient and accurate algorithms that can recover the phase of non-interferometric optical fields without the need for interferometers or other complicated setups. IntroductionPhase retrieval is afundamental problem in optics : that has attracted asignificant amount of research interest over the past few decades. The goal of phase retrieval is to estimate the phase of an optical wavefront from its intensity measurements, which can be extracted using adetector. The importance of phase retrieval arises from the fact that most optical signals carry information in their phase, and thus, areliable phase recovery is crucial for many optical applications, such as imaging, holography, and optical testing. For interferometric optical fields, phase retrieval can be relatively straightforward, since the phase can be inferred from the interference fringes produced by the superposition of two or more wavefronts. However, for non-interferometric optical fields, such as those produced by asingle wavefront, phase retrieval is much more challenging. This is because the intensity measurements alone do not contain sufficient information to uniquely determine the phase of the wavefront. Despite the difficulty of the problem, many researchers have proposed various algorithms for phase retrieval of non-interferometric optical fields. These algorithms typically rely on iterative optimization techniques to search for asolution that satisfies both the measured intensities and some additional constraints on the wavefront. However, most of these algorithms suffer from some drawbacks, such as slow convergence, sensitivity to noise, and difficulties in handling large-scale problems.
