Example one
Referring to fig. 3 and 4, the present application provides a holographic imaging structure comprising a display screen 101, a first holographic medium 102, a first image source, a second holographic medium 103, and a second image source.
The display screen 101 is used for displaying a foreground picture; a first holographic medium 102 and a second holographic medium 103 are arranged in connection in the direction of the display screen 101 towards the viewer. As shown in the figure, the direction close to the viewer is set to be the front direction (the direction E shown in fig. 4 is the front direction), the first holographic medium 102 and the second holographic medium 103 are located at the front direction, the display screen 101 is located at the rear direction, and the first holographic medium 102 and the second holographic medium 103 may be specifically holographic films or holographic phantom glass, both of which have strong reflectivity for reflecting the image and high transparency, so that the viewer can view the image displayed on the rear display screen 101 through the holographic films.
The height direction of the first holographic medium 102 and the height direction of the second holographic medium 103 are aligned with the height direction of the display 101, and as shown in fig. 3, the display 101 is vertically installed on a reference surface, for example, the floor of a stage, and the first holographic medium 102 and the second holographic medium 103 are also vertically installed on the floor. The space required by imaging is located above the ground, and sinking processing is not required to be carried out on the ground, so that the holographic imaging structure can be applied to various field situations. Compared with the prior art, in the scheme of the application, the sinking ground is not formed between the viewer and the holographic imaging structure, the visual presentation effect cannot be damaged, and the safety is higher.
The first holographic medium 102 and the second holographic medium 103 form a first preset included angle, the first holographic medium 102 and the display screen 101 form a second preset included angle, and the second holographic medium 103 and the display screen 101 form a third preset included angle; the first image source is positioned on one side of the first holographic medium 102 far away from the display screen 101, so that light is incident to the first holographic medium 102; the second image source is located on a side of the second holographic medium 103 remote from the display screen 101 such that light is incident on the second holographic medium 103. The first holographic medium 102 and the second holographic medium 103 are used to display a background picture.
Specifically, the light of the first image source is reflected by the first holographic medium 102 to form a first part of a background picture, the light of the second image source is reflected by the second holographic medium 103 to form a second part of the background picture, the first part and the second part are combined together to form a complete background picture, the background picture is a virtual image and is imaged behind the display screen 101 (within a range outlined by a dashed line in fig. 4), namely, the foreground picture and the background picture are separated by a certain distance, and the depth between the two pictures enables a viewer to feel that the picture in front of the eyes has a strong stereoscopic impression, so that a naked-eye 3D stereoscopic image display effect is presented in the whole device.
The first holographic medium 102 and the second holographic medium 103 form a folding structure and are arranged in front of the display screen 101, and compared with a holographic medium in a plane structure form, for displaying a background picture with the same width, the distance between the front end of the holographic medium and the display screen 101 can be reduced by the arrangement mode, the front-back distance of the whole structure can be reduced to half of the original distance at most, so that the device is more compact in structure and more suitable for being applied in small places.
Optionally, the first preset included angle is 90 degrees, and the second preset included angle and the third preset included angle are both 45 degrees. For the virtual image formed after the light of the first image source is reflected by the first holographic medium 102 and the virtual image formed after the light of the second image source is reflected by the second holographic medium 103, the planes where the two virtual images are located are parallel and can be parallel to the plane where the image displayed by the display screen 101 is located, so that the front and back parallel image texture with the sense of depth is formed.
Further, the first holographic medium 102 and the second holographic medium 103 form an axisymmetric structure with a joint of the first holographic medium 102 and the second holographic medium 103 as a symmetry axis.
In this embodiment, the first holographic medium 102 and the second holographic medium 103 are equal in size and convenient to process and install, and both form virtual images which are half of the background picture, so that the installation and setting of the first image source and the second image source are also convenient.
In an alternative scheme of this embodiment, one end of the first holographic medium 102 away from the symmetry axis is connected to one end of the display screen 101 in the width direction, and one end of the second holographic medium 103 away from the symmetry axis is connected to the other end of the display screen 101 in the width direction. That is, the folding structure formed by the first holographic medium 102 and the second holographic medium 103 is buckled in front of the display screen 101, so that the distance between the front end of the holographic medium and the display screen 101 can be further reduced, and the device structure is more compact.
In an optional scheme of this embodiment, the heights of the first holographic medium 102, the second holographic medium 103 and the display screen 101 are equal. That is to say, the sum of the projection areas of the first holographic medium 102 and the second holographic medium 103 on the plane where the display screen 101 is located is equal to the area of the display screen 101, and the maximum area of the background picture formed by the first holographic medium 102 and the second holographic medium 103 is the area of the display screen 101, so that the background picture and the foreground picture are arranged in a matching manner, the amount of the holographic medium is saved, and the cost is further saved. Referring to fig. 4, a is shown as the width of the first holographic medium 102 and the second holographic medium 103, C is the width of the display screen 101,

In this embodiment, the first shielding member 104 and the second shielding member 105 can shield the side surfaces of the display screen 101, the first holographic medium 102 and the second holographic medium 103, and only the viewing window 106 is left right in front of the whole device, so that the viewer can see the foreground picture and the background picture, thereby improving the visual effect of the viewer; and the first blocking member 104 and the second blocking member 105 can also avoid the interference light from influencing the picture effect of the display screen 101, the first holographic medium 102 and the second holographic medium 103.
Meanwhile, the first shielding member 104 and the second shielding member 105 also have the function of forming an image source, and particularly, the inner walls of the first shielding member 104 and the second shielding member 105 can be arranged into a curtain for displaying pictures projected by the projector so as to form the image source; alternatively, the inner walls of the first shielding member 104 and the second shielding member 105 may be configured as a display screen, and the image displayed by the display screen is the image source.

As can be seen from the data disclosed in the above embodiments, the included angle between the second shielding plate 108 and the first holographic medium 102 is 45 degrees, the first image picture is formed on the inner wall of the second shielding plate 108, and the first holographic medium 102 can reflect the first image picture to form a virtual image. The size range of the inner wall of the second shielding plate 108 is not smaller than the size range of the projection of the first holographic medium 102 to the second shielding plate 108, so as to ensure that the first holographic medium 102 is completely shielded from the side direction, and avoid the interference light from being incident on the first holographic medium 102.
Similarly, a second image picture is formed on the inner wall of the fifth shielding plate 111, and the size range of the inner wall of the fifth shielding plate 111 is not smaller than the size range of the projection of the second holographic medium 103 to the second shielding plate 108, so as to avoid the interference light from being incident on the second holographic medium 103.
