phase retrieval
Phase retrieval is a technique used to reconstruct an image or signal when only partial information is available, typically the intensity of light rather than its phase. In fields like optics and imaging, scientists often capture data that tells them how bright the light is but not its phase (which affects how waves combine). By using mathematical methods, researchers can infer the lost phase information and recreate the original image or signal. This process is crucial in various applications, from improving medical imaging to enhancing the performance of telescopes in astronomy.

Phase retrieval is a technique used to reconstruct an image or signal when only partial information is available, specifically lacking phase information. In optics, for example, we can measure the intensity of light waves but struggle to capture their phase. By using mathematical methods and algorithms, researchers can recreate the lost phase, allowing them to generate a clearer image or retrieve data. This process is crucial in fields like microscopy, X-ray imaging, and astronomy, where obtaining complete information is challenging but necessary for accurate analysis and understanding.
