Abstract
We report diffractive optical networks to replace the digital image reconstruction schemes in quantitative phase imaging (QPI) systems with a series of passive diffractive surfaces that perform phase recovery all-optically, completing the reconstruction of the QPI signal as the light is diffracted through thin structured layers. A diffractive QPI network all-optically maps the input phase information into an intensity distribution that reveals the QPI signal at the speed of light. With their compact footprint, diffractive QPI networks offer ultra-fast all-optical computation and low-power operation, demonstrating a new phase imaging concept that can be especially transformative for on-chip microscopy and sensing.
