41. Simbad A Calibration Using a Laser Based Facility and Comparison With Previous Techniques
Published: 2/1/2003
Authors: N Souaidia, Steven W Brown, Bettye C Johnson
Abstract: Two multi-channel filter radiometers were calibrated using three different techniques: against a lamp-illuminated integrating sphere source, against a laser-illuminated integrating sphere source and by cross-calibration against a primary sun photomet ...

42. 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 ...

47. Development of a Portable Integrating Sphere Source for the Earth Observing System's Calibration Validation Programme
Published: 1/1/2003
Authors: Steven W Brown, Bettye C Johnson
Abstract: We have designed and built a portable integrating sphere source to be used at NASA satellite sensor calibration facilities in support of the EOS calibration validation program. The source is designed to complement existing detector-based radiance v ...
