How to use holographic projection, how to do holographic projection

How to make a holographic projection? First prepare a few transparent cards, then divide them, then assemble them into an inverted pyramid, and finally you are ready.

How to use a simple holographic projection gadget.

Cut 4 isosceles trapezoids, 1cm at the top and 6cm at the bottom, and connect them into a funnel shape, at this time each side is at an angle of 45 degrees to the horizontal plane, and then put it on the phone, turn on a specific hologram, and you can see a three-dimensional effect similar to a holographic projection. The essence is the reflection of light.

The application of holographic projection technology in stage art can not only produce three-dimensional aerial illusions, but also enable the illusions to interact with the performers to complete the performance together and produce shocking performance effects. The use of a new perspective has attracted people's attention and aroused consumers' desire to consume. As one of the most interactive merchants in the Shanghai World Expo, Fuxiang Technology has first-class R&D strength in this technical field.

Holographic projection technology is a technology that uses the principle of interference and diffraction to record and reproduce the recording and reproduction of the real three-dimensional image of an object.

Step 1: Prepare the materials.

Transparent CD case, graver, grid paper, scotch tape, pen, ruler.

Step 2: Make a display.

1. Make four identical isosceles trapezoids on grid paper, with a top bottom of 1cm, a bottom of 6cm, and a height.

2. After cutting off the four trapezoids, fix them to the transparent CD case.

3. On the CD box, cut off the trapezoids.

4. Use scotch tape to glue the edges of the trapezoid.

Step 3: Start the experience.

Then, dim the surrounding lights and you'll be able to see the beautiful picture!

How to do holographic projection is explained as follows:

Find a clear plastic plate or a transparent empty bottle, and use a knife or scissors to cut through the middle.

Leave a part close to the mouth of the bottle, then cut it again with scissors near the mouth of the bottle, and scrape the edge of the new cut with a knife after cutting it to avoid scratching your hands.

Divide the funnel-shaped transparent part into four parts, and fold it along the selected corner line for extrusion.

After all four corners are extruded, press the back of the scissors again to keep their shape fixed.

After pressing the four sides, then put the smaller side of the countertop in the middle of our mobile phone**material (holographic**material to a certain sound on a search), if it is not flat or the table is larger than the middle part, you can use a knife to repair it.

Holographic projection technology is a popular high-tech technology in recent years, it is a kind of promotion means of using a kind of holographic film imported from abroad with projection and then adding image content to display products. It provides magical holograms that can be imaged on glass or acrylic materials. This new interactive display technology integrates decoration and practicality, and is completely transparent when there is no image, giving users a new interactive experience, becoming one of the most fashionable means of product display and marketing today.

Thotho Multi Interactive provides a variety of multi-display equipment.

Here's how to make a holographic projection:

1. Draw a circle with a compass. The compass should be bought and there is a pointed end, pull out the tip and insert the refill to draw.

2. Draw five radii with sharp things, that is, draw 4 corners, each 70 degrees.

3. Draw the strings at the center of the circle to form four triangles with a top angle of 70 degrees, and then cut them out.

4. Paste it with transparent glue so that we get a quadrangular pyramid.

7. The desktop and the surrounding area are best black, you can make a stand, the black desktop on the picture, and the background is the pen case.

1. Introduction to holographic projection

Holographic projection technology is a kind of 3D technology, which originally refers to the technology that uses the principle of interference to record and reproduce the real three-dimensional image of an object. Later, with the guidance of science fiction films and commercial promotion, the concept of holographic projection gradually extended to commercial activities such as stage performances and exhibitions.

However, the holograms we usually know are often not holographic projection in the strict sense, but a holographic projection technology that uses Pepper's magic macro Li Xiang, edge blanking and other methods to achieve 3D effects.

"Holo" comes from the Greek word "holo", which means "complete information", that is, it contains information about the amplitude and phase of the light waves. Ordinary photographic techniques only record the intensity (amplitude) of the light, while the depth information (phase) is lost.

In the interference process of holographic technology, the superposition of wave peaks and peaks will be higher, and the superposition of peaks and troughs will be flattened, so a series of irregular, light and dark stripes will be generated, so that the phase information will be converted into intensity information and recorded on the photosensitive material.

2. Extended classification

Holographic technology can be subdivided into optical holography technology, digital holography technology, computational holography technology, microwave holography technology, reflection holography technology, sound holography technology and so on. In various fields such as display, measurement, encryption, and identification, our common traditional holographic technology is optical holographic technology.
