Hyperspectral Image Projector for Advanced Sensor Characterization

December 4, 2006
Author(s)
Steven W. Brown, Joseph P. Rice, Jorge E. Neira, Bettye C. Johnson
In this work, we describe radiometric platforms able to produce realistic spectral distributions and spatial scenes for the development of application-specific metrics to quantify the performance of sensors and systems. Using these platforms, sensor and

Development of Hyperspectral Image Projectors

November 1, 2006
Author(s)
Joseph P. Rice, Steven W. Brown, Jorge E. Neira
We present design concepts for calibrated hyperspectral image projectors (HIP) and related sources intended for system-level testing of instruments ranging from complex hyperspectral or multispectral imagers to simple filter radiometers. HIP, based on the

Spectrally Tunable Sources for Advanced Radiometric Applications

October 1, 2006
Author(s)
Steven W. Brown, Joseph P. Rice, J D. Jackson, Jorge E. Neira, Bettye C. Johnson
A common radiometric platform for the development of application-specific metrics to quantify the performance of sensors and systems is described. Using this platform, systems may be quantified in terms of the accuracy of measurements of standardized sets

Hyperspectral Image Projectors for Radiometric Applications

March 23, 2006
Author(s)
Joseph P. Rice, Steven W. Brown, Bettye C. Johnson, Jorge E. Neira
We describe a new type of Calibrated Hyperspectral Image Projector (CHIP) intended for radiometric testing of instruments ranging from complex hyperspectral or multispectral imagers to simple filter radiometers. The CHIP, based on the same digital mirror

Flow visualization of heated CO2 gas using thermal imaging

January 1, 2006
Author(s)
Joseph P. Rice, Howard W. Yoon, M H. Brenner, N R. Briggs, J G. Gillen
Walk-through portal detection systems are being developed to screen passengers for the presence of explosives in support of homeland security. These portals utilize a series of air-jets to remove the explosive particles for detection using ion mobility

NIST Reference Cryogenic Radiometer Designed for Versatile Performance

January 1, 2006
Author(s)
Jeanne M. Houston, Joseph P. Rice
We describe the concept of modularity and versatility in the construction of a new cryogenic radiometer developed at NIST. We address the benefits of the modular design in the construction and development and discuss some of the device characterizations

The Miami2001 Infrared Radiometer Calibration and Intercomparison. Part I: Laboratory Characterization of Blackbody Targets

February 1, 2004
Author(s)
Joseph P. Rice, James J. Butler, B C. Johnson, P J. Minnett, K A. Maillet, T J. Nightingale, S J. Hook, A Abtahi, C J. Donlon, I J. Barton
The second calibration and intercomparison of infrared radiometers (Maiami2001) was held at the University of Miami Rosenstiel School of Marine and Atmospheric Science (RSMAS) during May-June 2001. The participants were from several groups involved with
