Reference Data Set of Human Skin Reflectance

June 7, 2017
Author(s)
Catherine C. Cooksey, David W. Allen, Benjamin K. Tsai
This data set contains 100 reference reflectance spectra of human skin, spanning the wavelength region from 250 nm to 2500 nm. The spectra were acquired with a commercial spectrophotometer and are directly traceable to the national scale for directional

Validating In-Air Remote Sensing Reflectance Measurements During Cruises Using Reflectance Targets

October 25, 2016
Author(s)
Bettye C. Johnson, Catherine C. Cooksey, Ahmed El-Habashi, David English, Georgi T. Georgiev, Sherwin Ladner, Veronica P. Lance, Michael Ondrusek, Ryan Vandermeulen
Annual dedicated ocean color validation cruises off the East Coast of the USA were started in November 2014 with support from the NOAA office of Marine and Air Operations with primary focus on VIIRS/SNPP and upcoming JPSS missions. A portion of the

2016 Topical Meeting on Optical Interference Coatings: Manufacturing Problem Contest

October 21, 2016
Author(s)
Catherine C. Cooksey, Daniel Poitras, Li Li, Michael Jacobson
For the Manufacturing Problem contest held in conjunction with OSA’s 2016 Topical Meeting on Optical Interference Coatings, participants were asked to design and fabricate on a provided substrate a coating with very specific (and rather peculiar)

National Institute of Standards and Technology measurement service of the optical properties of biomedical phantoms: Current status

March 24, 2016
Author(s)
Paul Lemaillet, Catherine C. Cooksey, Zachary H. Levine, Adam L. Pintar, Jeeseong Hwang, David W. Allen
The National Institute for Standards and Technology (NIST) has maintained scales of reflectance and transmittance over several decades. Those scales are primarily intended for the regular transmittance, mirrors, and solid surface scattering diffusers. The

SPIE 9639-49 Creation and Validation of Spectralon BRDF Targets & Standards

October 12, 2015
Author(s)
Catherine C. Cooksey, Gael Obein, Georgi T. Georgiev, Christopher Durell, Dan Scharpf, Greg McKee, Michelle L'Heureux
Spectralon is an extremely stable, near-perfect lambertian reflecting diffuser and calibration standard material that has been used by national labs, space, aerospace and commercial sectors for over two decades. New uncertainty targets of 2% on-orbit

Spectral reflectance variability of skin and attributing factors

May 21, 2015
Author(s)
Catherine C. Cooksey, Benjamin K. Tsai, David W. Allen
Knowledge of the spectral reflectance signature of human skin over a wide spectral range will help advance the development of sensing systems for many applications, ranging from medical treatment to security technology. A critical component of the

Bidirectional reflectance scale comparison between NIST and PTB

May 1, 2015
Author(s)
Catherine C. Cooksey, Maria E. Nadal, David W. Allen, Kai-Olaf Hauer, Andreas Hoepe
A comparison of bidirectional reflectance scales between the National Institute of Standards and Technology (NIST) and the Physikalisch-Technische Bundesanstalt (PTB) has been performed. Measurements of two sets of white diffuse reflectance standards, two

Sensor Calibration and Characterization to Meet Climate Monitoring Requirements

April 24, 2014
Author(s)
Catherine C. Cooksey, Gerald T. Fraser, Howard W. Yoon
The challenge of detecting small changes in the Earth's climate system over decadal and longer time scales places stringent requirements on environmental monitoring systems. Sensors must be well calibrated and maintain their calibration in challenging

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
