Training plan offered by the researcher Alejandro Ferrero Turrión and entitled: Light and its interaction with matter: measurement and applications
Registration deadline until April 12

The research group "Optical Radiation Measurements" of the Institute of Optics "Daza de Valdés" of the CSIC (IO-CSIC) has extensive experience in the field of radiometry and photometry, and for a decade it has also specialized in the detailed study of the reflectance of materials, from the most common to those with more complex optical properties. Accurate knowledge of reflectance, with good angular, spectral and spatial resolution, is very important to develop specific reflectance models for specific surfaces, as well as to establish the relationship between objective optical measurements and subjective visual attributes (color, brightness, translucency or texture) that give appearance to the visible world.

During the enjoyment of this research aid, the student will have the opportunity to become familiar with the laboratory instruments and components necessary for the measurement of optical radiation, with the radiometric and photometric magnitudes, and with the most complex and fundamental magnitudes for the characterization of the reflectance of opaque objects (bidirectional reflectance) and of translucent objects (bidirectional and bispositional scattering). He will experiment with the Spanish Gonio-Spectrophotometer (GEFE) and learn about the multitude of applications it supports.

It is expected that the student can carry out an investigation, at least preliminary, on the use of a scientific camera for the realization of bidirectional reflectance patterns. At present, these reflectance patterns are made with conventional detectors without spatial resolution (photodiodes) and require the measurement of the solid angle of observation or illumination, for which high precision apertures and a very exact knowledge of the distance of the detector (or light source) to the pattern. The use of a scientific camera would be more versatile and would provide much more information on the sources of uncertainty.
At the end of this training period, the student will have acquired experience in the use of radiation detectors and light sources, in the control of scientific instrumentation and in data processing. He will have a deep knowledge of the methodology of the measurement of optical radiation, and will have known a wide range of applications where this type of research is required and in which our group is active.
