Two special panels were organized. In the first week the panel was dedicated to the activities of ICO, ICTP, and RIAO, and possible interesting information for young researchers on future activities. During the second week panel, devoted to ICSU Latin-American regional office activities, Dr Manuel Limonta delivered a presentation on the four ICSU scientific strategic plans, namely, Biodiversity, Natural Hazards and Disaster Risks, Sustainable Energy and Mathematics Education. Also discussed was the center ICTP-MAIS (Meso-American Institute for Science), located in Ocozocoautla de Espinosa, in Chiapas, Mexico. The two directors of ICTP-MAIS, Arnulfo Zepeda and Ely Santos described the structure and research lines of this institute devoted to theoretical physics, mathematics and applications to energy.

A visit to the Irazú volcano provided a very special taste of a splendid geographical area that sustains no less than 5% of the Earth’s biodiversity. This meeting also represented a good opportunity for networking with other regional scientific institutions for future collaboration activities.

ICO is grateful to all scientific institutions and commissions that support this initiative, and to UCR, for the wonderful hospitality and remarkable efficiency in providing infrastructure.

It is expected that the activity will continue, and the organization of a second workshop is under consideration as a natural extension of the unique ICO/ICTP/TWAS joint venture.

Last, but not least, ICO expresses its deepest gratitude to Prof. Fernando Quevedo, executive director of ICTP, for supporting globally the materialization of this initiative since its inception.

Ten years of perseverance and meticulous research activities led satellite optics and photonics at the Centro de Investigaciones Opticas (CIOp) from zero to a height of 657 km, in the words of Mario Garavaglia. The Argentinian Satellite SAC-D/Aquarius was launched on 10 June 2011, carrying navigation and attitude control systems, and microwave water radiometers designed, and built with the active participation of CIOp researchers and students. The satellite SAC-D was developed in collaboration with NASA and other space agencies. They also contributed to calibration of the NIRST (New Infrared System Technology) cameras built in collaboration with Brazil. Mario Garavaglia, ICO Galileo Galilei awardee in 1995, has been responsible for all of these developments and has led a group of young engineers in the construction of four interference fibre optic gyroscopes mounted in a non-orthogonal and redundant structure. 

Every year the ICO Argentinian Territorial Committee organizes TOPFOT, a Workshop of Optics and Photophysics, which this year was in its 8th year. It was preceded by a meeting of students in Optics and Photophysics (EEOF) organized by the Young Opticians and Photophysicists of Argentina (JOFA) and by the SPIE and OSA student chapters of CIOp-University of La Plata, with participation of additional students from the University of Buenos Aires. The activities were attended by 130 participants.

Several Argentinian authorities participated in TOPFOT. Fernando Hisas from the Comisión Nacional de Actividades Espaciales (CONAE) inaugurated the event with a talk on the Argentinean Space Program placing emphasis on the successful experience of the co-operation with the local Scientific and Technological System, and other space agencies, in particular NASA, and ASI from Italy. Juan Plá from the Comisión Nacional de Energia Atómica (CNEA) reported on solar panels based on III-IV semiconductors that were developed and integrated at CNEA for the SAC-D.

CIOp has 24 researchers, physicists and engineers whose interests cover a variety of topics in optics and photonics. During the last year the work on movie encryption by Roberto Torroba, Néstor Bolognini and Myrian Tebaldi has received much international attention, being listed in several occasions as the most downloaded from OSA. Their papers “All-optical encrypted movie”, “Pure optical dynamical color encryption” and “Experimental multiplexing of encrypted movies using a JTC architecture” refer to dynamical encoding of images. The first one appeared in OSA’s Spotlight on Optics and was considered as leading to new ways of confronting this problem.

Angela Guzmán, ICO secretary general, had the opportunity to meet the event organizer and ICO territorial representative Marcelo Trivi and with the ICO territorial committee members during her stay in La Plata and to solicit their input regarding the future of ICO for the Strategic Planning Committee meeting in Genoa on 1–2 July.



Traveling lecturer from Germany to El Salvador

Prof. Annette Ladstaetter-Weissenmayer from Bremen was hosted by Prof. Carlos Rudamas in El Salvador.

A group of participants in the series of lectures “Physics and Chemistry of the Environment” held in SanSalvador, El Salvador.

Prof. Annette Ladstaetter-Weissenmayer from the Institut für Umweltphysik of the Universität Bremen (IUP-Bremen) visited San Salvador from 10 to 13 April. She was hosted by Carlos Rudamas and gave a series of lectures entitled “Physics and Chemistry of the Environment”. Lectures took place in the Auditorium of the Centro de Investigación y Desarrollo en Salud 

(CENSALUD) of the Universidad de El Salvador (UES) in San Salvador, the capital city of El Salvador in Central America.

The activity was carried out within the framework of the co-operation between the IUP-Bremen and the UES, and was co-sponsored by the Faculty of Natural Sciences and Mathematics of the UES and by the International Commission for Optics (ICO) within the ICO-Travelling Lecturer Program. This was also an activity of the Central American DAAD-Alumni Network for Research (CADAN:R) in El Salvador.

The main goal of the lectures was to motivate and educate Salvadorian students and professionals in the application of optical techniques in environmental sciences. This is very important because environmental pollution is one of the most important problems to solve in El Salvador. Her lectures were attended by 32 students of physics, geophysics, chemistry, biology and engineering and by university teachers from the UES departments of physics, chemistry and mathematics as well as by professionals working at the Salvadoran Ministry of Environment and Natural Resources (MARN).

Environmental physics, environmental chemistry and remote sensing techniques were the main topics covered during the lectures. After each sub-topic, students had the opportunity to solve the exercises of the “e-learning module on the remote sensing of nitrogen dioxide from space” ( This module is part of the ACCENT-TROPOSAT-2 (AT2) project, which is the Satellite Remote Sensing Task of ACCENT, the European Network of Excellence on Atmospheric Composition Change. Prof. Ladstaetter-Weissenmayer is one of the authors of this module. The students had the opportunity to discuss the content of this e-learning module with one of the leading scientists in this field. It also meant that Prof. Ladstaetter-Weissenmayer had the opportunity to interact in quite a personal way with all of the students that attended the lectures. The students and Prof. Ladstaetter-Weissenmayer also visited several laboratories located at the Faculty of Natural Sciences and Mathematics and the Faculty of Agricultural Sciences where research is conducted in fields related to the main topics of the lectures. They also visited the Environmental Observatory of the Salvadoran Ministry of Environment and Natural Resources. During this week of lectures, meetings were organized to work on the preparation of future activities of scientific co-operation in environmental sciences applying optical techniques and the preparation of a postgraduate study program in this field. The series of lectures “Physics and Chemistry of the Environment” has been organized by Prof. Carlos Rudamas and his research group at the Escuela de Física (Department of Physics) of the Universidad de El Salvador.
