Abstract: Embodiments are directed to polarization-splitting cameras that are capable of generating multiple polarization images as part of a single image capture operation, where each polarization image corresponds to a different polarization state of light received by the polarization-splitting camera. Specifically, the polarization-splitting cameras described herein may include a metasurface assembly that includes a first metasurface layer and a second metasurface layer. The first metasurface layer is configured to image light from different portions a field of view of the polarization-splitting camera to different regions of the second metasurface layer, and the second metasurface is configured to split this light based on its polarization state.

Abstract: An assay device is disclosed comprising a housing and a test portion, electronic circuitry and an optical assembly each a least partially located in the housing. The test portion comprises one or more test zones adapted to receive an analyte and a fluorescent label associated with the analyte, the fluorescent label being excitable by excitation light and adapted to emit emission light upon excitation by excitation light. The electronic circuitry comprises one or more light sources and one or more light detectors. The optical assembly comprises one or more excitation light guides adapted to guide excitation light from the one or more light sources to the one or more test zones, and/or one or more emission light guides adapted to guide emission light from the one or more test zone to the one or more light detectors.
