A Brief Discussion on the Advantages and Applications of Holographic Imaging

Holographic image What is the technology? What are its characteristics? How to achieve dynamic three-dimensional display of images? We need to start from two important parts, holography and display, to understand carefully. Holographic image We know that to express the three-dimensionality of an object, it is necessary not only to record the light intensity of the object's surface, but also to reflect the light of the object, which is important information.

I know that if these two pieces of information overlap, it will be to add a three-dimensional sense of shadow to a Chinese plane object (similar to the expressionist technique in still life sketching in art) in order to achieve it.

Holographic imaging is achieved by recording the above two types of information simultaneously during photography. Using a laser as the illumination light source, the light emitted from the light source is divided into two beams. One beam directly shines on the photosensitive plate, and the other beam is reflected on the subject and reflected on the photosensitive plate. Two light beams overlap on the photosensitive film to produce interference, and the photosensitivity of each point on the photosensitive film depends not only on the intensity but also on the phase correlation of the two light beams. Therefore,

Not only the reflection intensity of the object is recorded, but also the phase information. Holographic technology records more information than ordinary photographic technology, so it provides a much larger capacity than ordinary photos (more than times). Holographic image The display is achieved by illuminating the hologram with a light source. The frequency and transmission direction of this light are exactly the same as the reference beam, and the three-dimensional image of the object can be reproduced. Because the audience can see many aspects of the object from different angles, but only can't see it, it's just a video. 100 At present, the most commonly used light source is a projector. Because the brightness of the light source is relatively stable. Secondly, the projector has the function of magnifying images, which is very useful for holographic display.

    Holographic image What are the advantages? Let's analyze it now.

　The reconstructed three-dimensional image is conducive to the preservation and collection of precious art materials.

　  Holographic image During shooting, all points are recorded at any point on the hologram, and once the photo is damaged, it doesn't matter.

　　1. Holographic image Holographic photos have a strong sense of three-dimensionality and realistic images, and can be displayed at various exhibitions through lasers to achieve very good results.

　　2. With the advancement of science and technology and the development of the times, people's quality of life has also improved with the development of the times, and the requirements for everything in life are getting higher and higher, pursuing the convenience and enjoyment of high-end emerging technologies, and human beings' requirements for new display technologies are also getting higher and higher.

　　3. The technology is currently the most popular high-tech display imaging technology, providing wonderful display technology, a technology different from other display imaging technologies.

　  随着科学技术的进步，时代的发展，人们的生活质量也随着时代的发展而日益提高，对生活中一切的要求也越来越高，追求高端新兴技术的便利和享受，人类对新的显示技术的要求也越来越高。 Holographic image 技术是目前最流行的高科技显示影像技术，提供奇妙的显示技术，与其他显示影像不同的技术。
