Problems solved by technology

The disadvantage of one-time virtual image imaging is that the magnification of the video image is limited. If you want to increase the magnification, you must increase the number of lenses or the size of the display, which greatly increases the cost and weight, and makes the pixels of the display with low resolution Meta interferes more with vision
And to increase the resolution, the cost is greatly increased

Embodiment Construction

[0033] The principle of the present invention is as figure 1 , figure 2 , image 3 Shown: secondary magnification near-eye large viewing angle imaging system consists of backlight source 19, backlight cover 20, condenser mirror A16, condenser mirror B17, display 9, rhombic reflector 1, projection lens A2, projection lens B3, projection lens C4, projection lens D5 , composed of a flat mirror 6, a projection screen 7, a magnifying eyepiece A13, and a magnifying eyepiece B14.

[0034] During implementation, the single-eye secondary magnification near-eye large viewing angle imaging display system is composed of a backlight 19, a backlight cover 20, a condenser A16, a condenser B17, and a display 9 is connected to form. The second magnification system formed by the eyepiece A13 and the magnifying eyepiece B14 is parallel. The display 9 back faces a rectangular plane sandwiched by the right angle and the oblique angle of the rhombic reflector, and the other rectangular plane is...

Abstract

The invention relates to a design method for big visual angle imaging device of close observing video influence. The feature is that the lens observing body has display, projection lens, reflector, projection screen, and amplifying eyepiece. The display is video display, and lens cover and condensing lens of reflecting back light source are contained at the back of display liquid circuit. The invention makes the display have big visual angle displaying effect, and it is low cost, light, etc.

Description

technical field [0001] The invention relates to a design method of a large viewing angle imaging device that provides the effect of near-eye watching video, in particular a design method of a secondary zoom near-eye large viewing angle imaging device. Background technique [0002] The imaging principle of the existing speculum-type viewing device or glasses-type display is a magnified optical virtual image imaging, that is, to achieve the clear vision distance that the human eye can normally watch. The previous devices all use optical imaging that can generate magnified virtual images. Lenses, no matter whether these lenses belong to a coaxial eyepiece type magnifying optical system, an off-axis free-form internal reflection optical system, or an off-axis splitting magnifying optical system, and regardless of the number of components of these optical lenses. The disadvantage of one-time virtual image imaging is that the magnification of the video image...
