Abstract

Quantitative Phase Imaging (QPI) enables non-destructive, real-time, label-free imaging of transparent specimens and can reveal information about their fundamental properties such as cell size and morphology, mass density, particle dynamics, and cellular fluctuations. Development of high-performance and low-cost quantitative phase imaging systems is thus required in many fields, including for on-site biomedical imaging and industrial inspection. Here, we propose an ultra-compact, highly stable interferometer based on a single-layer dielectric metasurface for common path off-axis digital holography, and experimentally demonstrate quantitative phase imaging. The interferometric imaging system leveraging an ultrathin multifunctional metasurface captures image plane holograms in a single shot and provides quantitative phase information of the test samples for extraction of its physical properties. With the benefits of planar engineering and high integrability, the proposed metasurface-based method establishes a stable miniaturized QPI system for reliable and cost-effective point-of-care devices, live cell imaging, three-dimensional topography, and edge detection for optical computing.
