Compensation of aberrations in holographic microscopes: main strategies and applications

Abstract Digital holography is a technique that provides non-invasive, label-free, quantitative, and high-resolution imaging employable in biological science of matter fields, but not only. In the last decade, digital (DH) has undergone very significant signs progress made it one most powerful metrology tools. However, important issues to be afforded solved for obtaining quantitative phase information about analyzed specimen related aberrations. Sources aberrations can diverse, several strategies have been developed tested make DH reliable optical system with submicron resolution. This paper reviews effective robust methods remove or compensate retrieved by DH. Different are presented discussed detail on how such disturbing Among various improvements setups considered numerical algorithms, hybrid methods, recent Artificial Intelligence (AI) approaches all which affect improve quality accuracy reconstruction images’ procedures.
