Abstract
Edge enhancement and polarization detection are critical to image transparent or low-contrast samples. However currently available systems are limited to performing only a single functionality. To meet the requirement of system integration there is a pressing need for a microscope with multiple functionalities. Here we propose and develop a microscope with three different functionalities based on spatial multiplexing and polarization splitting. A novel geometric metasurface (MS) is used to realize a spiral phase profile and two phase gradient profiles along two vertical directions which can perform such an extremely challenging optical task. This is the first demonstration of a 3-in-1 microscope that can simultaneously obtain five images with different optical properties in an imaging plane for the same sample. Imaging experiments with different samples verify its capability to simultaneously perform edge imaging polarimetric imaging and conventional microscope imaging. Benefiting from the compactness and multifunctionality of the optical MS device the integration does not increase the volume of the microscope. This approach can enable users to visualize the multiple facets of samples in real-time. ? 2023 The Authors. Published by American Chemical Society.
