121. Spectrally Tunable Sources for Advanced Radiometric Applications
Series: Journal of Research (NIST JRES)
Published: 10/1/2006
Authors: Steven W Brown, Joseph Paul Rice, J D Jackson, Jorge Enrique Neira, Bettye C Johnson
Abstract: 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 standardize ...

122. Spectrally tunRadiometric Measurement Comparison on the Inte applications
Published: 1/1/2006
Authors: Steven W Brown, J D Jackson, Bettye C Johnson, Jorge Enrique Neira, Joseph Paul Rice

123. Stray Light Characterization for MOBY
Published: 2/1/2002
Authors: Bettye C Johnson, Steven W Brown, Keith R Lykke, M Feinholz, M Yarbrough, S Flora, D K Clark
Abstract: The Marine Optical Spectrograpli (MOS) system is used as a down-welling irradiance and up-welling in-water radiance profiler in two configurations: as the sensor for the Marine Optical Buoy (MOBY) and as a mobile, sliipboard-deployable sensor. Both ...

124. Stray Light Correction Algorithm for Spectrographs
Published: 1/1/2003
Authors: Steven W Brown, Bettye C Johnson, M E Feinholz, M A Yarbrough, S J Flora, Keith R Lykke, D K Clark

125. Stray Light Correction of the Marine Optical System
Published: 1/1/2009
Authors: M Feinholz, S Flora, M Yarbrough, Keith R Lykke, Steven W Brown, Bettye C Johnson, Dennis Clark
Abstract: The Marine Optical System is a spectrograph-based sensor used in the Marine Optical Buoy for the vicarious calibration of ocean color satellite sensors. It is also deployed from ships in instruments used to develop bio-optical algorithms that relate ...

126. Stray Light and Ocean Color
Published: 1/1/2003
Authors: Steven W Brown, Bettye C Johnson, N Souaidia, R A Barnes, D K Clark
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=104334

127. Stray Light and Ocean Color Remote Sensing
Published: 1/1/2003
Authors: Steven W Brown, Bettye C Johnson, N Souaidia, R Barnes, D K Clark
Abstract: Instruments used to make radiometric measurements of the ocean are typically calibrated against incandescent sources with a spectral distribution that peaks in the near-infrared, while the radiant flux from the ocean peaks in the blue to green spectr ...

128. Stray light correction algorithm for multi-spectral hyperspectral spectrographs
Published: 6/1/2012
Authors: Michael Feinholz, Stephanie J Flora, Steven W Brown, Yuqin Zong, Keith R Lykke, Mark A. Yarbrough, Bettye C Johnson, D. K. Clark
Abstract: An algorithm is developed to correct a multi-channel fiber-coupled spectrograph for stray or scattered light within the system. The efficacy of the algorithm is evaluated based on a series of validation measurements of sources with different spectra ...

129. Stray-Light Correction Algorithm for Spectrographs
Published: 2/1/2003
Authors: Steven W Brown, Bettye C Johnson, M Feinholz, M Yarbrough, S Flora, Keith R Lykke, D K Clark
Abstract: In this work, we describe an algorithm to correct a spectrograph's response for stray light. Two recursion relations are developed: one to correct the system response when measuring broad-band calibration sources and a second to correct the response ...

130. Stray-Light Correction of the Marine Optical Buoy
Published: 6/1/2003
Authors: Steven W Brown, Bettye C Johnson, S Flora, M Feinholz, M Yarbrough, R Barnes, Y S Kim, Keith R Lykke, D K Clark
Abstract: In ocean-color remote sensing, approximately 90% of the flux at the sensor originates from atmospheric scattering, with the water-leaving radiance contribution the remaining 10 % of the total flux. Consequently, errors in the measured top-of-the atm ...
