随着社会的发展，科学的进步，全息投影技术已经走出了理论，迈入了使用的殿堂，其不仅在工业、医疗、军事中得到使用，更是在教育、文化、娱乐中大放异彩。今天青岛全息投影小编就带大家了解一下全息投影技术如何呈现立体图像。

With the development of society and the progress of science, holographic projection technology has stepped out of the theory and entered the palace of use. It is not only used in industry, medical treatment and military, but also in education, culture and entertainment. Today, Qingdao holographic projection editor will show you how holographic projection technology presents stereoscopic images.

       全息投影秀它实际上属于一种光学错觉技术，它的原理并不复杂。通熟易懂的解释就是利用光技术，采集三维信息，即立体地全方位地采集物体信息，然后将这些信息立体地三维地复原给观众看，这种立体视觉的呈现效果奇特，科技感十足，营造了亦幻亦真的氛围，让观众真正能体验一把虚拟与现实的双重世界。

Holographic projection show is actually an optical illusion technology, its principle is not complex. The familiar and easy to understand explanation is to use light technology to collect three-dimensional information, that is, to collect object information in a three-dimensional and all-round way, and then restore the information to the audience in a three-dimensional way. This kind of three-dimensional vision has a unique presentation effect, full of sense of technology, and creates an illusion and real atmosphere, so that the audience can really experience a dual world of virtual and reality.

       全息投影内容制作多番考量视觉效果，在创意内容、画面色调、构图、明暗、节奏把握等方面进行艺术的再创造。同时通过将一些具有渲染情感的特效融入片源中，调动观者的情感。

The production of holographic projection content considers the visual effect many times, and recreates the art in creative content, picture color, composition, light and shade, rhythm control, etc. At the same time, some special effects with rendering emotion are integrated into the film source to mobilize the emotion of the viewers.

       其第一步是利用干涉原理记录物体光波信息，此即拍摄过程：被摄物体在激光辐照下形成漫射式的物光束；另一部分激光作为参考光束射到全息底片上，和物光束叠加产生干涉，把物体光波上各点的位相和振幅转换成在空间上变化的强度，从而利用干涉条纹间的反差和间隔将物体光波的全部信息记录下来。记录着干涉条纹的底片经过显影、定影等处理程序后，便成为一张全息图，或称全息照片。

The first step is to use the interference principle to record the light wave information of the object, which is the shooting process: the object is radiated by the laser to form a diffuse object beam; the other part of the laser beam is used as a reference beam to shoot on the hologram, which overlaps with the object beam to produce interference, and transforms the phase and amplitude of each point on the object light wave into the varying intensity in space, so as to make use of the inverse between the interference fringes Difference and interval record all the information of light wave. The negative recording the interference fringes becomes a hologram, or hologram, after being developed and fixed.

       其第二步是利用衍射原理再现物体光波信息，这是成象过程：全息图犹如一个复杂的光栅，在相干激光照射下，一张线性记录的正弦型全息图的衍射光波一般可给出两个象，即原始象（又称初始象）和共轭象。再现的图像立体感强，具有真实的视觉效应。全息图的每一部分都记录了物体上各点的光信息，故原则上它的每一部分都能再现原物的整个图像，通过多次曝光还可以在同一张底片上记录多个不同的图像，而且能互不干扰地分别显示出来。

The second step is to reproduce the light wave information of the object by the diffraction principle, which is the imaging process: the hologram is like a complex grating. Under the coherent laser irradiation, the diffraction light wave of a linearly recorded sine hologram can generally give two images, namely, the original image (also called the initial image) and the conjugate image. The reconstructed image has strong stereoscopic sense and real visual effect. Each part of the hologram records the light information of each point on the object, so in principle, each part of the hologram can reproduce the whole image of the original object, and multiple different images can be recorded on the same negative film through multiple exposures, and can be displayed separately without interference.

       全息投影主要分为两种形式，一种是幻影成像，还有一种是全息柜展示，不同的展示形式效果也不一样。

Holographic projection is mainly divided into two forms, one is phantom imaging, the other is holographic cabinet display, and different display forms have different effects.

       幻影成像。幻影成像是180度视角的，能够生动形象的讲述一个历史故事的发展或是一个产品的生成过程，让人们随着情节的深入了解介绍的内容，深受人们喜爱。

Phantom imaging. Phantom imaging is a 180 degree perspective, which can vividly tell the development of a historical story or the generation process of a product, so that people can understand the content of the introduction with the in-depth understanding of the plot, deeply loved by people.

       全息柜展示。全息柜常见的有270度和360度两种，270度全息柜能够让人们从三面观看产品的展示，360度全息柜则可以全方位的观看，让人们360度无死角的进行观看并且还可以有互动元素，成像效果立体直观。

Holographic cabinet display. There are two kinds of common holographic cabinets: 270 degree and 360 degree. The 270 degree holographic cabinet enables people to watch the display of products from three sides, while the 360 degree holographic cabinet enables people to watch in all directions, allowing people to watch 360 degrees without dead angle, and also has interactive elements. The imaging effect is stereoscopic and intuitive.

       相信大家看完以上内容以后，应该也了解全息投影技术是如何呈现立体图像了吧，希望会对大家有所帮助吧。

I believe that after reading the above content, you should also understand how holographic projection technology presents stereoscopic images. I hope it will help you.
