See at which congress, workshop, conference etc. we will be present and meet us there.

EANS2023 Congress | Barcelona (ES)








The European Association of Neurosurgical Societies (EANS) Annual Congress is the main meeting point of the European Neurosurgical Community, and the connecting link between European Neurosurgery and all continental neurosurgical societies. The Congress theme this year is “Neurosurgery and Technology at the service of Humanity”. This event will take place at the Palau de Congressos de Barcelona in Barcelona from September 24 – 28, 2023. The HORAO team will be presenting two Oral ePosters and displaying two ePosters. 

BIOAM-2023 | Palaiseau (FR)


September 13 – 15, 2023

The Biophotonics and Optical Angular Momentum (BIOAM) Workshop is providing a forum for researchers from both academia and industry working in various domains related to optical angular momentum (spin and orbital), including fundamental aspects, polarimetric instrumentation and applications. This event took place at the premise of Ecole polytechnique in Palaiseau from September 13 – 15, 2023 and was partly organised by the HORAO team. The HORAO team was therefore presenting several posters and giving Oral talks.   

SPIE Optics + Photonics | San Diego (USA)


August 2 – 24, 2023

The Society for Photographic Instrumentation Engineers (SPIE) Optics + Photonics Congress is the leading multidisciplinary optical sciences and technology meeting where the optics and photonics community share their latest advances in optical engineering, nanotechnology, quantum science, organic photonics and astronomical instrumentation.. This event took place at the San Diego Convention Center from August 20 – 24, 2023. The HORAO team was presenting at the Polarization Science and Remote Sensing XI Conference and gave an Oral talk on “Complete Mueller polarimetry: Do we need it for biological tissues diagnosis? (Invited Paper)”.  

ECBO | Munich (DE)


June 25 – 29, 2023

The European Conferences on Biomedical Optics (ECBO) is the premier European event bringing together scientists, engineers, and clinicians who work with optics and photonics to solve problems in biomedicine. This event took place at the International Congress Center (ICM) in Munich from June 25 – 29, 2023. The HORAO team was present at the Emerging Technologies for Cell and Tissue Characterization Conference and gave an Oral talk on “Partial Mueller polarimetry for the complete optical diagnosis of biological tissue”.

SPIE Photonics West | San Francisco (USA)


January 28 – February 02, 2023

The Society for Photographic Instrumentation Engineers (SPIE) Photonics West Congress is the world’s premiere laser, biomedical optics and biophotonic technologies, quantum and optoelectronics event. This conference took place at the Moscone Center in San Francisco from January 28 – February 02, 2023. The HORAO team has been participating with 5 Oral talks.

Polarized Light and Optical Angular Momentum for Biomedical Diagnostics Symposium

  • Evolution of polarimetric parameters of cadaver brain tissue with time and formaldehyde fixation in wide-field Mueller matrix images (Speaker: Romain Gros)
  • Multi-domain cotraining for tissue segmentation in fixed and fresh brain tissue using Mueller polarimetry (Speaker: Richard McKinley)
  • Evaluation of light penetration depth for Imaging Mueller polarimeter operating in a visible wavelength range in reflection geometry: ex-vivo studies of healthy brain white matter (Speaker: Omar Rodríguez-Núñez)
  • Denoising diffusion networks applied to Mueller polarimetric images of brain tissue (Speaker: Stefano Moriconi)

Clinical and Translational Neurophotonics Symposium

  • Brain white matter fiber tracts identification using wide-field imaging Mueller polarimetry: Ex vivo studies in a surgery-like environment (Speaker: Leonard Felger)

Our highlight was that Romain Gros’ work was awarded as “Best Student Paper”. Congratulations!

5th SFCNS Congress | Basel (CH)


September 28 – 30, 2022

The Swiss Federation of Clinical Neuro-Societies (SFCNS) Congress took place at the Congress Center in Basel from September 28 – 30, 2022. The HORAO team has been participating with 3 ePosters at this congress with a clinical focus.
