Resolution-Enhanced Lensless Color Shadow Imaging Microscopy Based on Large Field-of-View Submicron-Pixel Imaging Sensors

摘要

We report a resolution-enhanced lensless color shadow imaging microscopy (RELCSIM) system based on large field-of-view (FOV) submicron-pixel imaging sensors. The physical pixel size of our custom made imaging chip is 0.95um × 0.95um, and the pixel-count is 25 millions (5120H × 5120V). By directly recording the shadow of the samples without any postprocssing, we have realized a microscope with a half-pitch resolution of ~1um and a FOV of ~25mm
