Jared J. Griebel,Soha Namnabat,Eui Tae Kim,Roland Himmelhuber,Dominic H. Moronta,Woo Jin Chung,Adam G. Simmonds,Kyung-Jo Kim,John D. van der Laan,Ngoc A. Nguyen,Eustace L. Dereniak,Michael E. Mackay,Kookheon Char,Richard S. Glass,Robert A. Norwood,Jeffrey Pyun +15 more
TL;DR: High quality imaging in the near (1.5 μm) and mid-IR regions using high refractive index polymeric lenses from these sulfur materials was demonstrated.
Journal ArticleDOI
Evolution of circular and linear polarization in scattering environments
John D. van der Laan,Jeremy B. Wright,David Scrymgeour,Shanalyn A. Kemme,Eustace L. Dereniak +4 more
TL;DR: This work quantifies the polarization persistence and memory of circularly polarized light in forward-scattering and isotropic (Rayleigh regime) environments; and for the first time, details the evolution of both circularly and linearly polarized states through scattering environments.
Journal ArticleDOI
Measuring resolution degradation of long-wavelength infrared imagery in fog
Brian J. Redman,Brian J. Redman,John D. van der Laan,Karl R. Westlake,Jacob W. Segal,Charles F. LaCasse,Andres L. Sanchez,Jeremy B. Wright +7 more
TL;DR: In this paper, a quantitative analysis of resolution degradation in the long-wave infrared regime is presented based on the calculation of the modulation transfer function from the edge response of a slant edge blackbody target in known fog conditions.
Journal ArticleDOI
Light transport with weak angular dependence in fog.
Brian Z. Bentz,Brian J. Redman,John D. van der Laan,Karl R. Westlake,Andrew Glen,Andres L. Sanchez,Jeremy B. Wright +6 more
TL;DR: A model based on a weak angular dependence approximation to the Boltzmann or radiative transfer equation that appears to be applicable in both the moderate and highly scattering regimes, thereby covering the applicability domain of both the small angle and diffusion approximations is developed.
Proceedings ArticleDOI
Optical characterization of the Sandia fog facility
TL;DR: By proving the capability, this work will enable the testing and validation of future fog penetrating optical systems and provide a platform for performing optical propagation experimentation in a known, stable, and controlled environment.
