Conference communications


TecnOPTO participated at RNO2018, Reunión Nacional de Óptica, the Spanish Meeting of Optics, held in Castellón, from July 3th to 6th.

María del Mar Sánchez imparted the conference entitled “Analizador de haces vectoriales mediante una red de difracción con codificación de láminas Q”, within the Simposium of Imaging Techniques.

Four other posters related to our research were presented at the conference.


AOIM XI group


Ignacio Moreno participated as invited speaker in the Workshop on Adaptive Optics for Industry and Medicine AOIM XI, organized by Pablo Artal and his group at the University of Murcia in March 2018, 4-7.

Our latest results on the adaptive generation and detection of vector beams by means of liquid crystal spatial light modulators were presented in a talk entitled “Polarization Diffractive Elements displayed in Liquid Crystal Spatial Light Modulators”.



pwSPIE - SEDOPTICAIgnacio Moreno attended Photonics West, in San Francisco, in February 2018, 2nd-7th. An invited talk was presented by Jeffrey A. Davis on our mutual collaboration entitled Polarization state vector beam spectrum analyzer using q-plates encoded onto a spatial light modulator at the SPIE OPTO conference  Complex Light and Optical Forces XII, chaired by Enrique J. Galvez, David L. Andrews, and Jesper Glückstad.

Ignacio Moreno, as the current President of the Spanish Society of Optics – SEDOPTICA, signed the renovation of the collaboration agreement with SPIE. The picture shows Dr. Maryellen Giger, 2018 SPIE President, signing the agreement with Ignacio.





RSEFMaría del Mar Sanchez gave a talk about the generation of vectors beams with q-plate devices at the Meeting of the Royal Spanish Physical Society held in Santiago de Compostela in July 2017, 17th-21st, within the Symposium of Quantum & Non-linear Optics.

In this presentation, Maria del Mar reviewed some of our recent works. In the first part of the talk she presented the  performance of q-plates, and their combination to build other effective q-plates. In the second part she described the  implementation of q-plates on spatial light modulators, as well as their combination with axicon elements to create vector Bessel beams where both the topological charge and the polarization state vary upon propagation.


Pascuala Garcia presented the communication entitled On axis programmable microscope using liquid crystal spatial light modulator at the SPIE Optical Metrology Conference, held in Munich in June 25th to 29th, 2017.

We presented two communications. María presented the invited communication entitled “Outreach activities on light science and technology at TecnOpto-UMH during the International Year of Light” at the conference Optics Education and Outreach IV. This communication reviewed all the activities we developed to commemorate the IYL. The corresponding proceedings can be found at: link.

And Ignacio presented the communication entitled “Physical and encoded Q-plates for the generation of switchable vector beams” at the conference Laser Beam Shaping XVII. This presentation reviewed our recent studies with q-plate devices. The corresponding proceedings can be found at: link.


Light & Color

Ignacio Moreno presented a communication at the international meeting Light & Color in Nature held in Granada in May-June 2016.

The communication was entitled “Eclipsed sunrise and other optical effects captured by MUDIC group of astronomy”, and it presented some of the pictures of optica phenomena captured by our friend José Manuel Villa, from MUDIC museum.





Ignacio Moreno presented an invited communication at the meeting SPIE Photonics Europe held in Brussels in April 2016.

welcome-lieberman-moreno-280The communication was entitled “Production of arbitrary polarized light beams with a liquid crystal spatial modulator”, and it was presented within the session Optical Micro- and Nanometrology. This communication reviews our recent advances in the design of polarization diffractive optical elements encoded onto a spatial light modulador system.
