Abstract

The invention relates to the technical field of virtual image imaging systems and discloses a virtual image imaging system with an anti-peep film. The system comprises an image source module, a lens in the imaging system, an observer position, a light trajectory, an outgoing light and an anti-peep film. Imaging light emitted by the image source module is reflected by a lens in the imaging system and the light trajectory is imaging light; and the light trajectory is reflected to the observer position by the lens in the imaging system. The image source module includes outgoing light. According to the invention, with the anti-peep film, the image source light is filtered partially by using the film with the anti-peep property, so that the outgoing light direction is controlled and thus the stray light emitted by the image source module is blocked; and thus the direction of the outgoing line of the image source is limited and the outgoing light is filtered. Therefore, special requirementson the incident light, the outgoing line, and the external interference light can be met; and the optical imaging quality of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of virtual image imaging systems, in particular to a virtual image imaging system with an anti-peeping film. Background technique [0002] A virtual image refers to the collection of points of intersection of the opposite extension lines of light emitted by an object after reflection or refraction. First, the virtual image is formed by converging the reverse extension lines of the actual light; second, the virtual image cannot be presented on the light screen at this position, and can only be observed through optical components. An imaging system with the above characteristics is called a virtual imaging system. Typical virtual imaging systems include: microscopes, telescopes, head-up displays, augmented reality displays, helmet-mounted displays, etc. Images viewed directly through these systems, or through eyepieces, are virtual images. [0003] In a specific virtual image system, due to the special requ...
