Advantages and disadvantages of holographic projection technology

With the development of technology, holographic projection technology has become more and more perfect, and it has been applied to various commercial activities or large-scale stage performances, playing a pivotal role. Like the Spring Festival Evening stage special effects, the star concert stage creation, the mall holographic projection display cabinet used to display jewelry, etc., are realized by holographic projection technology.

Holographic projection technology is an image that uses the interference of laser light waves to record images and reproduced images. We can watch the products displayed in 360 degrees without any dead angles, enrich the three-dimensional display technology, and bring more vision to people. Impact is like the shocking effect of a real object that changes in front of the eye but does not touch it.

Nowadays, many big production films support 3D technology, because its visual effects are realistic and shocking, so many TV consumers are engaged in the home projection, as long as a 3D projector is easy to experience 3D visual enjoyment at home, then the 3D projector uses What technology is it? What are its advantages and disadvantages? Today, the author will take you to find out what 3D projector technology is available today.

Holographic projection technology is a technology of virtual three-dimensional technology that achieves stereoscopic effects in terms of vision and hearing through the use of computer operations. The 3D effect achieved in the movie is a movie that uses the principle of binocular stereo vision to enable viewers to obtain a three-dimensional visual image from the screen.

Up to now, there are four types of relatively mature holographic projection technology. Color stereoscopic 3D, polarized 3D, stereoscopic 3D and the latest DLP Link technology. These four types of technologies are currently widely used holographic projection techniques. Due to their different principles, different costs and different effects, they also occupy different markets. Today we will focus on the advantages and disadvantages of these four main technologies.

1, color stereo three-dimensional

advantage:

Glasses are inexpensive, use simple filters, and have decades of proven technology for easy content creation.

Disadvantages:

The image quality is very poor, and it is mainly used in relatively inexpensive 3D display toys. Of course, compared to other technologies,

2, polarization three-dimensional

advantage:

The higher the original resolution, the better the picture quality will naturally be. At the same time, the cost of polarized glasses is relatively low, and the lowest is tens of dollars can be purchased.

Disadvantages:

1), need two projectors to use together, the cost increases,

2), the position of the two projectors needs to be accurately adjusted, and can not be moved at will, so the later maintenance is more troublesome.

3, stereoscopic 3D

advantage:

The image quality is good and does not require much additional equipment.

Disadvantages:

This specification has fewer sources, and the use of infrared transmission signals is easily limited by the viewing angle. Therefore, in order to allow viewers in different locations to see stable 3D images, it is necessary to add a large number of infrared emitters.

4, DLP Link

advantage:

1) The signal transmission is more stable and is not subject to the image of the angle of view.

2) Since there is no additional equipment added, the production cost of the projector will not increase, and only one pair of stereo glasses is needed.

Disadvantages:

Less 3D content affects the popularity of the technology.

Bimetal Thermometer

Bimetallic thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the thermal expansion of the two metals is different, which drives the pointer to deflect to indicate the temperature. This is bimetallic sheet thermometer, as shown in the figure on the above page. The temperature measurement range is - 80 ~ 500C, which is suitable for temperature measurement when the accuracy requirement is not high in industry. As a temperature sensing element, bimetallic sheet can also be used for automatic temperature control.
