Holographic projection technology : What should be paid attention to when using holographic projection technology?

With the advancement of the times, the projection industry is also facing new opportunities and challenges. It is not limited to the simple projection mode of a traditional single projector with a computer and screen, but a projection display mode with features such as super-large screen, high pixel, multi-angle, and human-computer interaction. It brings a brand-new visual experience. So, holographic projection technology: What should be paid attention to when using holographic projection technology?

Holographic projection technology : What should be paid attention to when using holographic projection technology?

1. Use an interference light source. This point is achieved, that is, when applying holographic technology, use an interference light source, otherwise this technology will not work. First of all, holographic projection is effective because it makes full use of light and then performs other operations under the action of light. Therefore, it is necessary to ensure that the spatiotemporal coherence of this light is good, otherwise the holographic effect will be very poor.

2. System stability Because holographic technology comes from another field of photographic systems, their patterns are the same, but holographic films can record more information, so the final effect will be better. There will be many interference fringes on the holographic film, recording information about objects in various fields. If there is a problem with one interference fringe, the entire image will have problems. Therefore, when applying holographic imaging technology, it is necessary to ensure the stability of the photographic system, and there must be no mistakes during the shooting process, otherwise the entire image will be destroyed. It is necessary to ensure the stability of the internal system and the stability of the external environment. When making images, pay attention to the laboratory environment and try to avoid large fluctuations, otherwise it will affect the image effect in the later stage.

3. Sufficient light source. This technology will use a total of two light sources, object light and reference light. Under the action of these two light sources, the later image will be generated, so the necessity of object light and reference light is self-evident. First of all, it is necessary to ensure that the two light sources are sufficient, and secondly, to ensure that the optical path difference is small, because it is impossible to achieve zero optical path difference, so try to make the optical path difference small. In addition, the angle between the two light sources should be kept at a certain level as much as possible, which is 45 degrees. If there is a gap, do not exceed 15 degrees. In addition, the ratio of light intensity is also very important, and standard operating procedures must be strictly followed.

Another point is to pay attention to the application of high-resolution films and make full use of holographic projection technology to display images closely related to the films. High-resolution films can make the projected images clearer, and the overall display effect will be better.
