Abstract

This project aims carrying out researches about photosensitive materials in order to get a deeper knowledge about the mechanisms and processes that lead to the recording of light in these material. Such a knowledge will allow us to improve the performance of these materials and better use them for different applications such as holographic optical component and micro and/or nano structures fabrication, image processing, holographic and/or interferometric applications to mechanical vibration measurement, etc. In order to achieve these objectives it will be necessary to closely coordinate activities in different areas from fabrication and characterization until development of different applications for these materials. In order to achieve these objectives we rely on the work of an experienced team of scientists. The team includes experts in crystalline and amorphous materials and thin films fabrication, as well as on materials characterization and optical applications. Among the materials that will be prioritarily focused upon are photo-electro-refractive crystals of the sillenite type, particularly oxide of bismuth and titanium that is excellent for image processing and is already produced in Brazil with a very good optical quality. Other materials like photoresists and photosensitive glasses will be also researched. Until the conclusion of this project we expect to have aquired a good deal of knowledge about these materials and the way optical recording is processed. We expect also to have been able to develop new interesting applications. (AU)
