A novel holographic device

Holographic equipment Projection technology is a 3D technology. Initially, it referred to the technology of recording and reproducing true 3D images of objects using the principle of interference. Later, under the guidance of science fiction films and commercial advertisements, the concept of holographic equipment projection gradually extended to commercial activities such as exhibitions and stage performances. However, the holography we usually understand is not strictly holographic projection, but a holographic projection technology that uses methods such as edge fading and Pepper's ghost to achieve 3D effects. Ordinary photographic technology loses depth information (phase) and can only record light intensity information (amplitude). In the interference process of holography, the superposition of peaks will be higher, and the superposition of peaks and valleys will become flatter, producing a series of irregular stripes of alternating light and dark, thereby converting phase information into intensity information and recording it on photosensitive materials. However, general Holographic equipment The structure is simple, and the projection effect is low due to irregular placement during use. General holographic projection equipment can only project and cannot play sound.

Technical points: Technicians provide a new type of Holographic equipment device to solve the problems raised in the above background technology. In order to achieve the above purpose, the holographic device adopts the following technical scheme: A holographic device technical device, including a base, fixed legs welded at the four corners of the bottom of the base; a connecting block bolted to the top of the base; a projection screen is inserted into the outer wall of the connecting block; the projection screen includes a left projection screen, a right projection screen, a front projection screen, and a rear projection screen; a fixed block is welded to the outer wall of the bottom of the movable rod, and fixed locks are screwed at both ends of the movable rod, and an inverted trapezoidal receiver is inserted into the inner wall of the fixed block. Inverted trapezoidal receiver includes a right trapezoidal plate, a left trapezoidal plate, a rear trapezoidal plate, a front trapezoidal plate, and a bottom fixed plate. A thread cooperating with the fixed lock is provided on the movable rod, and the left trapezoidal plate is connected to the bottom fixed plate at 45 degrees, with a height 3.5 times the length of the short side and a long side 6 times the length of the short side. The connecting block is provided with a card slot matching the projection screen. The left projection screen and the right projection screen are opposite to each other, and the front projection screen and the rear projection screen are opposite to each other. The number of vertical rods is two, and they are welded in parallel to the top of the connecting block. The number of fixed blocks is two, and the distance between the fixed blocks is the same as the inverted trapezoidal receiver bottom length.

Compared with the existing technology, the above Holographic equipment has the following beneficial effects:

1 、The new holographic device welds fixed legs at the four corners of the base, welds a connecting block to the outer wall of the top of the base, welds a vertical rod to the top of the connecting block, connects the connecting block and the projection screen, connects the movable rod inside the vertical rod, welds a fixed block to the outer wall of the bottom of the movable rod, screws fixed locks at both ends of the movable rod, welds a sound synchronizer to the top of the movable rod, and inverts trapezoidal receiver is placed between the fixed blocks. Rotate the fixed lock to fix the inverted trapezoidal receiver position, push the movable rod to move the inverted trapezoidal receiver placed on the top outer wall of the projection screen, so that the inverted trapezoidal receiver can be perfectly projected. A sound synchronizer is set to play sound simultaneously with the projection, enhancing the visual experience. Fixed legs are set to make the base stable, and fixed blocks are set to make the inverted trapezoidal receiver placed in the center of the projection screen.

2 、The left trapezoidal plate is glued to the left, the right trapezoidal plate is glued to the right, the front trapezoidal plate is glued to the front, and the rear trapezoidal plate is glued to the rear. According to the connection direction of the trapezoidal plate, the projection screen is placed at the bottom of the inverted trapezoidal receiver so that the four sides of the projection screen are diffracted through the trapezoidal plate, making the projection effect clearer and more vivid.
