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
