Holograms: Principles and Techniques

With the legacy of the inventions of Lippmann, Gabor et al, we are lucky enough to have been the generation who have experienced the dawn of the age of holography first hand. Still, when we think of holograms, we think of the future, a place full of wondrous inventions. A place where driverless cars defy gravity, civilization is established on Mars, or cities are built under earth’s oceans. And then, of course, holographic images that materialize in thin air and communicate with each other using artificial intelligence, indistinguishable from human consciousness. Such is the legacy of science fiction. In reality, this vision of the future may fall far beyond the laws of physics, but nevertheless there are some truly astounding developments taking place right now in the field of holography right now. I know, because as a research professor at De Montfort University, I’ve had the privilege of experiencing some of the world’s most incredible three-dimensional holograms and it’s a glimpse into a future I want to share with you!
