We report on the design, modeling, calibration, and experimental results of a LWIR, spectrally and temporally resolved broad band bi-directional reflectance distribution function measuring device. The system is built using a commercial Fourier transf

Validating predictive models and quantifying uncertainties inherent in the modeling process is a critical component of the HARD Solids Venture program [1]. Our current research focuses on validating physics-based models predicting the optical propert

Remote detection of a surface-bound chemical relies on the recognition of a pattern, or “signature,” that is distinct from the background. Such signatures are a function of a chemical’s fundamental optical properties, but also depend upon its s

The combination of continuous-wave difference frequency generation based on quasi-phase-matched (QPM) gallium arsenide with cavity ring-down spectroscopy is explored for use in spectroscopic and chemical sensing applications. The advent of QPM materi

There has been some confusion in the published literature concerning the structure of Metastudtite (UO2)O2(H2O)2 where differing unit cells and space groups have been cited for this compound. Owing to the absence of a refined structure for Metastudti

Quasi-phase-matched (QPM) materials allow the generation of spectroscopically useful infrared radiation in an efficient and broadly tunable format. Here, we describe several applications of QPM-based light sources to remote and local chemical sensing

A cavity ringdown spectrometer is described that employs a novel mid-infrared light source based on periodically poled lithium niobate. The source generates tunable light using the three-step process of optical parametric generation, spectral filteri

The application of a new method for measuring velocity fields within a porous medium is presented. Fluid containing fluorescent microspheres is flowed through a transparent, refractive-index-matched column filled with 3.1 mm spherical beads. A planar

This work focuses on progress in gaining a better understanding of the polymorphic nature of the UO3 and UO3-water system; one of several important materials associated with the nuclear fuel cycle. The UO3-water system is complex and has not been ful
