This is laser holography
Did you see the deceased star suddenly appear on the stage on TV or small screen? It’s amazing, how is this done? In fact, this is the laser holography technology that is said today.
This is laser holography
Holographic technology is a technique that uses the principle of interference and diffraction to record and reproduce a true three-dimensional image of an object. By using the laser as an illumination source and splitting the light emitted by the source into two beams, the interference is superimposed on the photosensitive sheet, and finally the digital image is utilized. The hologram reproduced by the basic principle.
1. Holographic technology is a technique that uses the principles of interference and diffraction to record and reproduce real three-dimensional images of objects;
2. Holographic photography uses a laser as an illumination source, and splits the light emitted by the light source into two beams, one beam directly directed to the photosensitive sheet, and the other beam reflected by the object and then directed to the photosensitive sheet;
3. The two beams are superimposed on the photosensitive sheet to generate interference, and finally the hologram reproduced by the basic principle of the digital image is further processed to remove the digital interference and obtain a clear holographic image;
4. At present, the main application areas of holographic imaging technology: commercial display, stage performance, entertainment, art, education, media science, technology design, etc., in terms of stage applications, holographic imaging technology can not only produce three-dimensional aerial illusions, It also allows the illusion to interact with the performers and complete the performance together to produce a stunning performance.
