The Society for Photographic Instrumentation Engineers (SPIE) Photonics Europe Congress is the only cross-disciplinary event highlighting compelling optics and photonics technologies—from digital optics to quantum technologies to optical imaging, sensing, and metrology. Additional topics include THz photonics, 3D printed optics, photonic glasses, photosensitive materials, and biophotonics. This event took place at the Palais de la Musique et des Congrès in Strasbourg from April 7 – 11, 2024. The HORAO team has been giving two Oral talks: Estimation of light penetration depth in human brain tissue using wide-field imaging Mueller polarimetry – ex vivo study in formalin-fixed human cerebral white and gray matter (Omar Rodríguez Núñez) and (Romain Gros).

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 was “Neurosurgery and Technology at the service of Humanity”. This event took place at the Palau de Congressos de Barcelona in Barcelona from September 24 – 28, 2023. The HORAO team has been presenting two Oral ePosters and displaying two ePosters. 

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)”.  

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.
