Dr. Ignacio Moreno is Full Professor of Optics at University Miguel Hernández (UMH), in Elche, Spain. He received the degree in Physics and the PhD in Physics in 1992 and 1996 respectively, at the Autonomous University of Barcelona (UAB). His PhD thesis focused on the application of spatial light modulators (SLM) to optical correlators, supervised by Prof. María J. Yzuel and Prof. Juan Campos.
For two years (1996-98) he joined the Department of Optics of the University of Valencia (UV), and since 1998 he is at UMH. In 2020 he joined the UMH Institute of Bioengineering.
He has an extensive experience in the field of liquid crystal SLMs and their application in diffractive and polarization optics, having published more than 150 articles in peer reviewed journals. He maintains stable active collaborations with Spanish (UAB, UV) and international centers (San Diego State University, Institut FEMTO, Université de Franche-Comté, and Universidad de La Frontera).
He is Senior Member and Fellow Member of SPIE (2009 and 2014), and Senior Member and Fellow Member of OSA (2010 and 2017). In 2012 he received the EOS2012 Prize from the EOS – European Optical Society. In 2015 he became a grantee of the Fulbright Scholar Program.
In 2017-20 he was President of the Spanish Society of Optics – SEDOPTICA. Previously, in 2014-2017, he was the Vicepresident; in 2005-2014 he was editor of the journal Óptica Pura y Aplicada – OPA.
Since 2013 he is Associate Editor of the journal Optical Engineering. He has been Guest Editor of two special sections entitled Liquid Crystals for Photonics (2011), and on Spatial Light Modulators: Devices & Applications (2019).
Since 2017 he is Vicepresident of the Spanish Committee for the International Day of Light.
He was the Chair of the Organizing Committee of two meetings held at Elche: the 4th Spanish Meeting on Optoelectronics – Optoel’05 (July 2005) and the 3rd International Workshop on Liquid Crystals for Photonics (September 2010).

In the second part of this work, the method is experimentally highlighted by studying a rabbit leg ex-vivo sample. The obtained images of the ex-vivo sample illustrate how IPPs provide a significant enhancement in the image contrast of some biological tissues and, in some cases, present new information hidden in the usual polarimetric channels. Moreover, new physical interpretation of the sample can be derived from the IPPs which allow us to synthesize the depolarization behavior.
Finally, we also propose a pseudo-colored encoding of the IPPs information that provides an improved visualization of the samples. This last technique opens the possibility to highlight a specific tissue structure by properly adjusting the pseudo-colored formula.
The set-up has been experimentally implemented and some experimental concerns are discussed. The suitability of the system is provided by generating different experimental spatial distributions of polarization. In this regard, well-known polarization distributions, as axial, azimuthal or spiral linear polarization patterns are here provided. Based on the excellent results obtained, the suitability of the system to generate different spatially variant distributions of polarization is validated.
