1. Tunable Supercontinuum Fiber Laser Source for BRDF Measurements in the STARR II Gonioreflectometer
Heather J Patrick, Clarence Joseph Zarobila, Thomas Avery Germer, Victor Alan Ying, Catherine C Cooksey, Benjamin K Tsai
STARR II is a planned NIST facility for spectral measurements of specular reflectance and diffuse bidirectional reflectance distribution function (BRDF) that is the follow-on to the current NIST STARR (Spectral Tri-function Automated Reference Reflec ...
2. The evaluation of hyperspectral imaging for the detection of person-borne threat objects over the 400 nm to 1700 nm spectral region
Catherine C Cooksey, Jorge Enrique Neira, David W Allen
The detection of person-borne threat objects, such as improvised explosive devices, at a safe distance is an ongoing challenge. While much attention has been given to other parts of the electromagnetic spectrum, very little is known about what potent ...
3. SWIR calibration of spectralon reflectance factor
Catherine C Cooksey, Georgi T Georgiev, James J Butler, Leibo Ding, Kurtis J Thome
Satellite instruments operating in the reflective solar wavelength region require accurate and precise determination of the Bidirectional Reflectance Factor (BRF) of laboratory-based diffusers used in their pre-flight and on-orbit radiometric calibra ...
4. Investigation of the potential use of hyperspectral imaging for stand-off detection of person-borne IEDs
Catherine C Cooksey, David W Allen
Advances in hyperspectral sensors and algorithms in numerous fields of research have opened up new possibilities for its use in the detection of person-borne IEDs. While portions of the electromagnetic spectrum, such as the x-ray and terahertz regio ...
5. NIST Measurement Services: Regular Spectral Transmittance
Special Publication (NIST SP)
David W Allen, Edward A. Early, Benjamin K Tsai, Catherine C Cooksey
This document describes measurement services, instrumentation, and measurement techniques for regular spectral transmittance over the spectral range from 250 nm to 2500 nm at the National Institute of Standards and Technology. Section 2 explains the ...
6. Workshop on Bridging Satellite Climate Data Gaps
Journal of Research (NIST JRES)
Catherine C Cooksey, Raju Vsnu Datla
Detecting the small signals of climate change for the most essential climate variables requires that satellite sensors make highly accurate and consistent measurements. Data gaps in the time series (such as possible launch delay or failure) or incon ...
7. Report on the NIST workshop of December 10, 2009: calibration strategies for bridging possible climate data gaps
Raju Vsnu Datla, Joseph Paul Rice, Catherine C Cooksey, Kurtis J Thome, Robert Barnes, Changyong Cao
A one day workshop was held on December 10, 2009 at the National Institute of Standards and Technology to address the issue of data gaps in the time series of satellite measurements. Such gaps can occur due to launch delay or failure, or inconsisten ...
8. Terahertz spectroscopy of aqueous L-Proline in reverse micelles
Catherine C Cooksey, Edwin J Heilweil, Benjamin Greer
A new method for obtaining room temperature terahertz (THz) absorption spectra of aqueous-phase biomolecules in the frequency range 1 THz to 21 THz (35 cm-1 to 700 cm-1) is reported. The spectrum for L-Proline was acquired by solvating the amino ac ...
