Broadband transmission filter 2013 OIC manufacturing problem contest

January 10, 2014

Author(s)

Catherine C. Cooksey, Li Li, J. A. Dobrowolski, Michael Jacobson

A broadband transmission filter from 400nm to 1100nm was selected for the manufacturing problem contest. The premise of the contest is to test the state of the art of current optical thin film manufacturing capabilities. A total 37 people from 15 teams

Reflectance measurements of human skin from the ultraviolet to the shortwave infrared (250 nm to 2500 nm)

May 29, 2013

Author(s)

Catherine C. Cooksey, David W. Allen

While published literature of the optical properties of human skin is prevalent for the visible region, data are sparse in the ultra violet and shortwave infrared. Spectral imaging has expanded from primarily an earth remote sensing tool to a range of

Tunable Supercontinuum Fiber Laser Source for BRDF Measurements in the STARR II Gonioreflectometer

September 27, 2012

Author(s)

Heather J. Patrick, Clarence J. Zarobila, Thomas A. Germer, Victor A. 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

SWIR calibration of spectralon reflectance factor

October 3, 2011

Author(s)

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 calibrations

NIST Measurement Services: Regular Spectral Transmittance

March 10, 2011

Author(s)

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 basic

Workshop on Bridging Satellite Climate Data Gaps

February 16, 2011

Author(s)

Catherine C. Cooksey, Raju V. 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

Report on the NIST workshop of December 10, 2009: calibration strategies for bridging possible climate data gaps

August 12, 2010

Author(s)

Raju V. Datla, Joseph P. 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 inconsistencies or

Terahertz spectroscopy of aqueous L-Proline in reverse micelles

November 21, 2008

Author(s)

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 acid
