Abstract:
We introduce an adaptive angle-calibration framework for mask-less on-chip phase imaging, where an LED array is used to deliver angled illuminations. Our framework accounts for spatially-varying illumination angles produced by each LED across expansive fields-of-view, enabling wide field-of-view phase imaging.
