Abstract

In order to obtain a high-resolution image and realize the all-day imaging simultaneously, a visible and long-wave infrared dual band imaging detector is proposed and designed, by a meta surface structure through which the infrared light has been absorbed and the visible light passed. With a monolithic chip, the visible light of 400 nm to 900 nm and the long-wave infrared light of 8 μm to 14 μm have been detected, which have the apparent size and weight advantages. This validates the improved integration of structure and results in considerable reduction of the complexity of the imaging system, which is advantageous to target recognition in complex environment.
