摘要：Implementation of holographic video calls in mobile devices using of hologram projectors additional to TFT displays. Here we use hologram projectors for video calls by storing video as holographic images through the method of Computer Generated Holography. Problem statement: Hologram video calls are not in usage, they are simply under research condition. Hologram makes video calls in 3D virtual display. In order to bring hologram usage in mobile phones by means of hologram projectors in the way of computer generated holography. Approach: Computer Generated Holography (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by suitable coherent light source. Alternatively, the holographic image can be brought to life by a holographic 3D display (a display which operates on the basis of interference of coherent light), bypassing the need of having to fabricate a "hardcopy" of the holographic interference pattern each time. Consequently, in recent times the term "computer generated holography" is increasingly being used to denote the whole process chain of synthetically preparing holographic light wave fronts suitable for observation. Holographic computer displays for a wide range of applications from CAD to gaming, holographic video and TV programs, automotive and communication applications (cell phone displays) and many more. Results: 3D hologram images are set in the video frames by hologram projectors while we make a video calls. Conclusion: By using the hologram projectors in the mobile phones. Holographic images are stored in the frames in vid eo. While making the video call 3D hologram video will be displayed through hologram micro projector. Voices are transmitted through microphones and speakers
