Monte Carlo Modeling of an Integrating Sphere Reflectometer

July 1, 2003
Author(s)
A Prokhorov, Sergey Mekhontsev, Leonard Hanssen
The Monte Carlo method has been applied to numerical modeling of an integrating sphere designed for hemispherical-directional reflectance factor measurements. It is shown that a conventional algorithm of inverse ray tracing used for estimation of

Low Scatter Optical System for Emittance and Temperature Measurements

October 1, 2002
Author(s)
Sergey Mekhontsev, Leonard M. Hanssen
The development and evaluation of an optical system for a new spectral directional emittance facility at NIST is reported. The imaging quality and signal contributions due to out-of-field-of-view scattering, commonly characterizedby the size-of-source
