The application discloses a micro-prism and black AR composite optical cover plate for aerial imaging and belongs to the technical field of medium-free aerial imaging optical devices. The cover plate is arranged above a flat lens, a glass substrate is divided into an inner bonding surface facing the flat lens and an outer visible surface, the inner bonding surface is provided with a one-way micro-prism optical structure, the two can be closely assembled or an assembly gap for adapting an optical path can be reserved, and the outer visible surface is provided with a multilayer medium interference light extinction black AR antireflection film layer. The micro-prism optical structure has four light field regulation functions: ensuring high transmission of oblique imaging light, shielding the micro-nano texture on the surface of the flat lens by total internal reflection of external vertically incident ambient light, correcting imaging geometric distortion by angle pre-compensation of the light emitted by the flat lens, and widening the effective viewing angle by outward divergence and beam expansion of the edge field of view. The application can obtain a regular and large field of view aerial real image without software pixel correction, has multiple functions of high light transmission, hidden texture, outer visible pure black appearance effect, distortion correction and large viewing angle, and can be applied to various aerial imaging devices for vehicles, households and businesses.
