▎ 摘　　要

NOVELTY - Graphene-based portable multifunctional binocular infrared night vision device comprises power supply, laser infrared light supplement lamp, display, left set of component and right set of component, where each set of component comprises lens, infrared filter layer, image intensifier and signal processing unit. The image intensifier comprises photocathode array for realizing photoelectric conversion, microchannel plate for realizing electron multiplication and fluorescent screen for electronic imaging, where photocathode unit in the photocathode array adopts photoelectric device consisting of semiconductor and graphene film, and graphene film is laid on the semiconductor. The graphene film comprises 40-60% of non-AB structure content and graphene structure based on weak coupling enhancement, where graphene structure comprises 60-70 graphene units stacked up and down along the thickness direction in the vertical direction, and upper and lower adjacent graphene units are weakly coupled. USE - Graphene-based portable multifunctional binocular infrared night vision device used in national defense military and civil commercial fields. ADVANTAGE - The portable multifunction meter with alkenyl graphite has high sensitivity to the infrared light, and improves the response distance of the night-vision device, improves sensitivity of the infrared response, and improves the use convenience and multi-functionality.
