Determinacion mediante termografía de la reflectancia infrarroja de materiales especulares

Abstract

En este trabajo se presenta una metodología experimental destinada a la medición de la reflectancia especular en el rango del IR lejano, mediante la utilización de una cámara termográfica. Las medidas se realizaron para muestras especulares de dos tipos diferentes: con soporte de vidrio y reflectores metálicos. Se estudiaron espejos de distintos espesores y calidad de vidrio, vidrios claros, acrílico y una placa de aluminio. Se determinó la reflectancia infrarroja de estos materiales para distintos ángulos de incidencia (10°, 30°, 45°, 60° y 70°). Los resultados indican que la muestra de aluminio presenta los mayores valores de reflectancia (0.80 a incidencia normal), que disminuye al aumentar el ángulo de incidencia. Las cinco muestras compuestas por vidrio presentan valores de reflectancia similares entre ellas (0.15 a incidencia normal), la cual aumenta con el ángulo de incidencia.

This work presents an experimental methodology to measure the specular reflectance in the far IR range, by using a thermographic camera. Measurements were performed for specular targets of two different types: with glass support and for metallic reflectors. Mirrors of different thicknesses and qualities of glass, clear glasses, acrylic and an aluminum plate were studied. For these materials the infrared reflectance was determined for different incident angles (10°, 30°, 45°, 60° and 70°). The results indicate that the aluminum target presents the highest values of reflectance (0.80 at normal incidence), which decreases as the angle of incidence becomes higher. The five samples that contains glass have similar reflectance values (0.15 at normal incidence), which increase with the incidence angle.
