Speaker
Description
This talk will introduce optical elements displayed with liquid-crystal spatial light modulators (SLMs). These pixelated microdisplays are useful for encoding optical phase functions and controlling the polarization of light. Modern SLMs exhibit high spatial resolution and precise control of optical retardance, allowing them to display diffractive elements. They have become key components for the generation and control of structured light. Combined with geometric-phase elements or with metamaterials provide new schemes for imaging or optical processing. The talk will present the main SLM technologies, their advantages and limitations, as well as different examples of how light can be controlled with them.
Ignacio Moreno is Full Professor of Optics at University Miguel Hernández (UMH), in Elche, Spain. He graduated in Physics (1992) and obtained the PhD (1996) at the Autonomous University of Barcelona. After two years at the University of Valencia, in 1998 he joined UMH, where he leads the TecnOPTO Lab. His research is centered in the use of liquid crystal spatial light modulators in diffractive and polarization optics, being coauthor of more than 180 articles in peer reviewed journals. He has been guest researcher at San Diego State University (USA), Institut FEMTO (France), Universidad de La Frontera (Chile) and the Military University of Technology (Poland). He is Fellow Member of SPIE and of OPTICA. He received the EOS2012 Prize from the European Optical Society (EOS). He has been Associate Editor of the journal Optical Engineering (2013-22), and President of the Spanish Society of Optics – SEDOPTICA (2017-2020). Since September 2024 he is the EOS President-Elect.
