Abstract
We have developed SiO2/AST arrays capable of multi-band photodetection and multispectral imaging by drawing inspiration from the sophisticated visual system of eagles. The optimized devices demonstrate exceptional optoelectronic perfor-mance, particularly the high figures of merit at 365 nm, achieving the P of 1.2 × 107 , R of 4.1 × 106 A W−1 , D* of 2.8 × 1017 Jones and the LDR of 141.6 dB. Building upon these fundamental characteris-tics, we successfully replicated the dynamic visual adaptation observed in eagles during high-speed flight and prey tracking maneuvers, the accuracy of object recognition up to 89.51%. Remarkably, the system maintains stable operation under varying illumination conditions, successfully reconstructing letter patterns through postsynaptic current mapping under both strong and weak light pulse stimulation. This work establishes a critical foun-dation for next-generation bionic vision systems and unlocks new opportunities for advanced multispectral imaging technologies.
