• Abstract: Adaptive optics (AO) has revolutionized imaging in {fields} from astronomy to microscopy by correcting optical aberrations. In label-free microscopes, however, conventional AO faces limitations due to the absence of guidestar and the need to select an optimization metric specific to the sample and imaging process. Here, we propose an AO approach leveraging correlations between entangled photons to directly correct the point spread function (PSF). This guidestar-free method is independent of the specimen and imaging modality. We demonstrate the imaging of biological samples in the presence of aberrations using a bright-field imaging setup operating with a source of spatially-entangled photon pairs. Our approach performs better than conventional AO in correcting specific aberrations, particularly those involving significant defocus. Our work improves AO for label-free microscopy and could play a major role in the development of quantum microscopes.

  Transport-of-Intensity Equation (TIE) often requires multiple acquisitions at different defocus distances. We propose to use chromatic aberrations to induce the required through-focus images with a single exposure. Our contributions offer an alternative TIE approach that leverages chromatic aberrations, achieving accurate single-exposure phase measurement with white light.

  A single neural network is difficult to handle all exposure problems. In particular, convolutions hinder the ability to restore faithful color or details on extremely over-/under- exposed regions. We propose a Macro-Micro-Hierarchical transformer, which consists of a macro attention to capture long-range dependencies, a micro attention to extract local features, and a hierarchical structure for coarse-to-fine correction.

  We investigate the application of genetic and machine learning approaches to tomographic problems. We find that the neural network-based scheme provides a significant speed-up, that may be critical in applications requiring a characterization in real-time. We expect these results to lay the groundwork for the optimization of tomographic approaches in more general quantum processes.

  High-resolution imaging of ultracold atoms typically requires custom high numerical aperture (NA) optics. We employ a low cost high NA aspheric lens as an objective for a practical and economical-although aberrated-high resolution microscope. We show that our digital correction technique reduces the contribution of photon shot noise to density-density correlation measurements.
