The 17th HOLOEXPO, 2020

September 2020

After Nizhny Novgorod in 2018 and St Petersburg in 2019, it was the turn of Moscow to host the 17th HOLOEXPO – the International Conference on Holography and Applied Optical Technology.

The conference sponsors read like a who’s who of Russian holographic companies, including KRYPTEN Scientific and Manufacturing Association from Dubna, HoloGrate LLC from St. Petersburg, CONTENANT Public Science and Technology Academy from Krasnogorsk, the State Institute of Applied Optics from Kazan and the Atlas Science and Technology Center, James River Branch LLC, Optical-Holographic Instruments LLC, and Alliance of Optical Systems LLC – all from Moscow.

The conference programme was comprised of 41 plenary and sectional reports, divided into the following thematic sections:

  • Technology in the field of security holograms – four reports;
  • Image-forming and displaying information using diffractive optics – four reports;
  • Hologram and diffraction optical elements: computer synthesis techniques; metamaterials, plasma structures and manufacturing technologies – five reports;
  • Volume holography and photosensitive materials for holography – six reports;
  • Holographic interferometry, holographic memory, optical-holographic information processing – six reports;
  • There were also 12 tabletop presentations at the conference.

Some of the highlights of the papers presented on security holograms included the development of features that use the formation of coloured holographic images with elements of movement and dynamics.

Polarising images that can be read by both conventional polarisers and automatic images using smartphones were featured, as well as recording/reading devices for personalised encoded hidden images, along with the introduction of new photosensitive materials for security holography – for example photopolymers and thin-film metamaterials.

In the field of diffraction and hologram optical elements, the conference reported on the introduction of new methods of computer synthesis of Fourier-Fresnel holograms and modern methods of computer modelling of these components, as well as the use of the latest photosensitive materials in the form of photo-thermo-refractive glasses with unique operational parameters.

Some of the other areas covered in the conference were holographic interferometry and microscopy, wave front sensors, correlational imaging recognition systems and holographic memory and the widespread adoption of digital holography techniques, digital hologram synthesis and holographic filters using modern megapixel spatial light modulators and multipixel high-speed photo-video cameras, allowing the creation of optical-holographic devices and coherent and non-chemical systems without the use of photographic materials.

Display holography also featured prominently in the conference, reporting on the widespread introduction of computer methods of synthesis of coloured 3D digital holograms, as well as the creation of mobile installations based on multi-coloured lasers to record colour holograms of historical objects of interest. There was also an exhibition of fine art Denisyuk holograms.

At the close of the conference, 25 honorary diplomas were awarded to organisations for active participation and sponsorship, as well as personal diplomas for excellence.
