Figure | Architecture and working principle of the proposed nanophotonic sensor. a Conceptual illustration of a bee and its compound eye structure consisting of numerous ommatidia arranged on a curved surface to achieve a wide field-of-view (FoV). b Illustration of a miniature unmanned aerial vehicle (MAV) equipped with PINS, inspired by the compound-eye structure. c Schematic of the sensor architecture. The core system integrates a metalens array, 550 nm optical filter, stray light-blocking mask, CMOS image sensor, and microcontroller unit, all enclosed within a compact 3D-printed modular housing. d Illustration of the imaging process using a wide-angle metalens array. e Phase profiles of the three metalenses in the metalens array. f Top and side views of the scanning electron microscopy (SEM) images of the fabricated nanostructures. g Schematic of wide-angle detection using the integrated MAV. h Process of motion detection and trajectory prediction using the sensor.
