4. Absorption Line Evaluation Methods for Wavelength Standards
Published: Date unknown
Authors: C Zhu, Leonard M Hanssen
Abstract: Two methods for absorption line (peak) evaluation based on center of gravity (CG) calculations are described and compared using spectra of the NIST standard reference material (SRM) 1921(a) characterization measurements. These methods are (1) calcul ...

5. Absorption and Reflection of Infrared Radiation by Polymers in Fire-Like Environments
Published: 7/17/2012
Authors: Gregory T Linteris, Mauro Zammarano, Boris Hannes Wilthan, Leonard M Hanssen
Abstract: In large-scale fires, the input of energy to burning materials occurs predominantly by radiative transfer. The in-depth absorption of radiant energy by a polymer influences its ignition time and burning rate. The present investigation examines two ...

9. Algorithmic Model of Microfacet BRDF for Monte Carlo Calculation of Optical Radiation Transfer
Published: 8/1/2003
Authors: A Prokhorov, Leonard M Hanssen
Abstract: An algorithmic model of bi-directional reflectance distribution function (BRDF) based on the ray optics approximation and microfacet model of randomly rough surface is proposed. Its central idea is that for every incident ray, the normal vector to t ...
