Intensity Measurement

Intensity measurement, the process of quantifying the strength of a signal or field, is crucial across diverse scientific disciplines. Current research focuses on improving the accuracy and efficiency of intensity-based reconstructions, particularly in challenging scenarios like phase retrieval (recovering a signal from its magnitude-only measurements) and diffraction tomography (reconstructing 3D refractive index maps from 2D intensity data). This involves developing advanced algorithms, such as those employing neural networks (including physics-driven and generative models) and leveraging novel sampling strategies to overcome limitations of traditional methods. These advancements have significant implications for various fields, including microscopy, astronomy, and materials science, enabling higher-resolution imaging and more accurate characterization of complex systems.
