3D Zero Order Imaging – the People’s Choice

As is the tradition, the winners of the Excellence in Holography 2022 Awards were judged by Board members of the International Hologram Manufacturers Association (IHMA) and presented as part of The Holography Conference Online.

But, also following tradition, it is the IHMA membership and conference attendees who get to vote online for their favourite technical advance in holography during the year. The ‘People’s Choice’ for 2022 was won by the Computer Holography Centre for a new holographic principle, called 3D Zero Order Imaging.

The new technology was presented during the conference by Anton Goncharsky, CHC General Director, providing a fascinating insight to the generation of new features that act like real 3D objects.

Rainbow, or Benton, holograms are a well-established method for forming 3D images that provide horizontal parallax but suffer chromatic aberration when inclined vertically and offer a very narrow range of viewing angles. The geometry of Benton’s approach also results in the image disappearing completely when the viewing angle exceeds a certain value.
