What is a holographic projector and how to choose one?

Holography is a method of recording information that is based on interference. - mutual increase or decrease in amplitude when the waves are superimposed on each other. In turn, hologram Is a three-dimensional image that is obtained using holography. This image has a sense of spatial depth and multi-angle. A hologram is created using a special device with a laser that reproduces an image of a three-dimensional object.

It is customary to call a holographic projector fan with controlled LEDs, which are located along the entire length of the blades.

In addition, using the built-in Wi-Fi module you can transfer your photos to this device and view them.

All types of holographic projectors are characterized by the following features:

• the presence of a special program for the operation of a computer (laptop);
• remote control;
• compact size;
• reading SD cards to quickly change content;
• use of bright LEDs for more realistic visualization;
• high image quality;
• quite large image coverage area.

All these features allow a wide use holographic projectors in many areas of modern life. At conferences, presentations, exhibitions in our time, 3D holograms are very often used. Marketing and advertising with their help successfully attract new customers.

When teaching with holograms, you can master new material as in theory and in practice... The entertainment industry also successfully uses this innovation: computer games, show business, nightclubs.

As already noted, to create a 3D hologram, you need at least two light waves... One of them is supporting, and the other goes to the object and is called object. In the role of waves in modern devices are used special lasers, at the intersection of which interference occurs, causing a three-dimensional picture.

Fan Projectors create an image as a result of rapid rotation, they are invisible to viewers. With the help of controllers, a series of light pulses are generated under a torque. As a result, we see a vivid three-dimensional image. In order to control such a device, you need to download a special application and run it.

To choose the right holographic projector, you should carefully read the following expert recommendations.

1. First decide for what purpose this device is purchased, how often it will be used, and which signal source it will connect to.
2. From light sources it is worth giving preference laser... It produces pure colors, has a huge resource and low energy consumption.
3. When using conventional projectors, take into account the fact that the more the room is lit, the higher the brightness should be. But when using holographic projectors, the resulting hologram is clearly visible in a room with any level of illumination.
4. Compact 3D fan It is easy to bring from the store and assemble it yourself, but in order not to spoil the device, carefully read the instructions.
5. It should be borne in mind that holographic fan the power consumption is lower than that of the holographic pyramid.
6. 3D fan - This is the most budgetary and quickest payback option among modern holographic projectors.
