    "Fourier lightfield multiview stereoscope for large field-of-view 3D imaging in microsurgical settings" (2025) https://www.spiedigitallibrary.org/journals/advanced-photoni... :

    > Abstract: We present the Fourier lightfield multiview stereoscope (FiLM-Scope). This imaging device combines concepts from Fourier lightfield microscopy and multiview stereo imaging to capture high-resolution 3D videos over large fields of view. The FiLM-Scope optical hardware consists of a multicamera array, with 48 individual microcameras, placed behind a high-throughput primary lens. This allows the FiLM-Scope to simultaneously capture 48 unique 12.8 megapixel images of a 28 × 37 mm field-of-view, from unique angular perspectives over a 21 deg × 29 deg range, with down to 22μm lateral resolution. We also describe a self-supervised algorithm to reconstruct 3D height maps from these images. [ to 11 μm ] [ ... ]

    48 x 12.8 megapixels = 614.4 megapixel lightfield microscope

      Very very cool! It would be nice to reject the surgical tool's "infinite depth" line of sight artefact with additional tool tracking logic but a really impressive demo.
