Problems solved by technology

[0005] At present, DCRA optical components have been used to realize aerial imaging, but they are limited to the precision requirements of optical components: DCRA optical components are composed of tiny mirrors with a size of 100 μm, and their processing accuracy needs to be within tens of nanometers, so they can only be used for small Aerial imaging of images, and processing costs are high
Current aerial imaging techniques for large imagery aren't really there yet

Embodiment 1

[0053] like Figure 1-2 The above-mentioned, an aerial imaging element, is a plurality of transparent spheres 1 coated with a reflective film 2 (spherical reflection surface) at the bottom neatly arranged on a horizontal plane, and the light passes through the reflective film 2 at the bottom of the transparent sphere 1 at least 2 times After reflection, an aerial real image corresponding to the incident image is formed. The diameter of the transparent sphere 1 (ie, the spherical reflection surface 2 ) is less than 1 mm.

[0054] The transparent sphere 1 is fixed on the cloth surface 4 (it can also be another plate-like object that can be pasted) through the adhesive layer 3 .

Embodiment 2

[0056] The aerial imaging display device including the aerial imaging element of Embodiment 1 further includes a projection device for carrying an incident image, the light generated by the incident image displayed by the projection device passes through the aerial imaging element to form a real image in the air. The display device includes a box body carrying the projection device, the upper end of the box body is provided with a semi-transparent mirror, and the inner wall of the box body is provided with an aerial imaging element (reverse reflection screen), such as: image 3 shown.

[0057]Preferably, the projection device can perform human-computer interaction in a wired or wireless manner.

Embodiment 3

[0059] like Figure 5-6 As shown, a teleprompter includes a main unit and a display screen, and the main unit is placed on the table 11 used by the announcer (or as Figure 7-8 Shown below the podium 14) or inside the table, the display screen is arranged under the table top, the host computer is connected to the display screen, and the table is provided with an aerial imaging element, and the aerial imaging element 12 (or Figure 8 The aerial imaging element 13) in the shown podium is arranged above the display screen, and the light of the text or image displayed on the display screen forms a real image R in the air through the aerial imaging element 12, and the announcer can directly see it without lowering his head.

[0060] Wherein, the aerial imaging element includes one or more optical elements 1 that bend the light of the incident image and form a real image in the air, the optical element is a transparent or semitransparent sphere with a reflective film on the bottom, ...

Abstract

The invention relates to the field of optical imaging, in particular to an aerial imaging element, an aerial imaging display device and applications thereof. In order to solve the above problems, the present invention provides an optical element with simple structure and low production cost, which is suitable for a large-scale aerial imaging display platform. An optical element that bends the light of an incident image, the bottom section of the optical element is a spherical reflective surface, and the light is reflected at least twice on the reflective surface at the bottom of the optical element to form a real image in the air corresponding to the incident image. The application of aerial imaging technology does not require any medium, and a real image can appear in the air where there is no real object. You can touch and operate the aerial image with your fingers, so as to realize a brand-new aerial imaging human-computer interaction system.

Description

technical field [0001] The present invention relates to the field of optical imaging, in particular to an aerial imaging element, an aerial imaging display device and applications thereof. Background technique [0002] With the development of science and technology, there are more and more applications of aerial imaging technology. [0003] At present, stereoscopic imaging technology can be divided into three categories: 1) binocular stereoscopic imaging technology, the stereoscopic image is composed of two images with parallax, and the audience needs to wear auxiliary devices to watch, such as binocular film viewer, red-green (or red-blue) ) glasses, polarizer glasses, liquid crystal light valve glasses, stereo helmet displays, etc.; 2) grating stereo image technology, the stereo image is synthesized by more than 2 images with horizontal parallax, and the audience can watch the stereo picture without wearing glasses, Widely used in multimedia display, advertising display, ...
