What was it for and how did it work?
For 60 years, high-energy pulsed lasers have enabled the recording of extremely realistic portraits of living people within a few nanoseconds. In the 21st century, this confidential technique, which requires great skill and equipment, has almost disappeared because of the final monochromatic color of the holograms, which does not appeal to the public. With this work, we show that ultra-realistic, full-color, and full-parallax snapshot holographic portraits can be recorded using multiple synchronized cameras. This project was successfully conducted using the digital CHIMERA™ holographic stereogram printing technique combined with image interpolation using a neural network. Only twelve cameras were required to record 34×44 cm, with 250 μm hogel resolution, full-parallax portraits.
What is significant about this hologram project?
For the first time ultra-realistic, full-color, and full-parallax snapshot holographic portraits can be recorded and it is a great advance compared to the previous techniques. This new recording method allows holographic portraits to be developed and disseminated to the public on a larger scale.
