This Web page gives you access to one of my main catalogues:
 

* My professional catalog, dealing with RESEARCH IN OPTICS AND HOLOGRAPHY.

* My catalog on TEACHING OPTICS.  (in portughese only)

* My personal one (in portughese), to deal with matters of MY DAILY LIFE, MY NEIGBOURHOOD, MY CITY. (in portughese only)

There is also information in esperanto, but for that you should have choosed esperanto at the index before this page. Although I do my best to bring you information, the more complete version is in Portughese, because I do not have time to translate all the material.
