Head-worn image amplification device

Abstract

The invention relates to the technical field of image displaying, in particular to a head-worn image amplification device. The head-worn image amplification device comprises an image amplifier, and the image amplifier comprises a signal source support used for containing a video signal source, a semi-reflection semi-permeable lens and a concave reflection magnifying lens. The semi-reflection semi-permeable lens is arranged on the light path of light which is emitted out by the video signal source and incident to the semi-reflection semi-permeable lens, and a certain included angle is formed. After the light generated by the video signal source is reflected to the concave reflection magnifying lens by the semi-reflection semi-permeable lens, the light passes through the concave reflection magnifying lens to form a virtual image amplified by several times, and the light penetrates through the semi-reflection semi-permeable lens to enter the pupils of an observer, and an amplified image amplified by several times relative to an original signal image is presented. Due to the adoption of the signal source separation scheme, the head-worn image amplification device is low in cost, light and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a head-mounted image magnifying device. Background technique [0002] In the prior art, most large-screen images rely on large physical screens, which cannot meet the requirements of light weight, portability, and low cost. Although the micro-projector in the prior art can solve the problem of portability, the micro-projector has high requirements on the ambient light intensity, requires a larger space, has higher production costs, and is not satisfactory in terms of definition and brightness. [0003] Traditional head-mounted video glasses are composed of an image display screen and multiple sets of optical lenses. This structure of head-mounted video glasses requires complex electronic circuits, expensive liquid crystal or other display devices, optical lens groups, and rechargeable lithium batteries. etc., the cost is very high, and it is impossible to enter the consump...

Problems solved by technology

[0003] Traditional head-mounted video glasses are composed of an image display screen and multiple sets of optical lenses. This structure of head-mounted video glasses requires complex electronic circuits, expensive liquid crystal or other display devices, optical lens groups, and rechargeable lithium batteries. etc., the cost is very high, and it cannot enter the consumption field of the general public

[0004] In view of the above problems, a new head-mounted image magnifying device is urgently needed to solve the problems of high cost, heavy weight and inconvenient portability of the head-mounted image magnifying device existing in the prior art
