摘要：
Lensless holographic microscopy offers a powerful route to high-content two- and three-dimensional imaging over large fields of view, but its broader use is often constrained by limited chemical specificity and by multiple scattering in optically dense samples. In this lecture, I will present a unified lensless imaging framework implemented on a standard CMOS camera and operating across an exceptionally wide spectral range, from deep ultraviolet (~240 nm) to the silicon cut-off (near 1100 nm). This platform enables high space-bandwidth product UV-absorption imaging of cells and tissue slices with intrinsic chemical contrast, near-infrared complex-field imaging with reduced scattering in turbid specimens, and multiple-scattering-aware phase tomography at gigavoxel scale. Together, these advances show how a simple on-chip platform can support computational microscopy and tomography across complementary spectral regimes, opening new possibilities for mesoscale information-rich imaging of highly heterogenous biomedical samples.
