Optical analysis of a linear-array thermal radiation detector for geostationary Earth radiation budget applications
Abstract (Summary)
The Thermal Radiation Group, a laboratory in the Department of Mechanical
Engineering at Virginia Polytechnic Institute and State University, is currently working to
develop a new technology for thermal radiation detectors. The Group is also studying the
viability of replacing current Earth Radiation Budget radiometers with this new concept.
This next-generation detector consists of a thermopile linear array thermal radiation
detector. The principal objective of this research is to develop an optical model for the
detector and its cavity. The model based on the Monte-Carlo ray-trace (MCRT) method,
permits parametric studies to optimize the design of the detector cavity and the
specification of surface optical properties. The model is realized as a FORTRAN
program which permits the calculation of quantities related to the cross-talk among pixels
of the detector and radiation exchange among surfaces of the cavity. An important
capability of the tool is that it provides estimates of the discrete Green’s function that
permits partial correction for optical cross-talk among pixels of the array.
Agradecimientos
Primero que todo quiero agradecer a mi “advisor” por su confianza ciega, apoyo
incondicional e inmensa paciencia, y a Dr E. P. Scott y Dr. T. E. Diller por su
disponibilidad para ser miembros de mi comité.
Quiero agradecer también a mis compañeros del Grupo de Radiación Térmica:
Katherine, Félix, Ira, Edwin, Joel y Stephanie, a mi paisano Juan Carlos y a los
cordobeses Raúl y Sergio, quienes sin su ayuda esto hubiera sido mucho más difícil sino
imposible. Al resto de mis amigos, muchas gracias por hacer de mi paso por Blacksburg
y Virginia Tech una experiencia placentera y enriquecedora.
Finalmente y de una manera muy especial, agradezco a mis padres y mi hermana
por el enorme apoyo y quienes a pesar de la distancia hicieron lo posible por hacerme
llegar su cariño y ánimo para seguir adelante.
