96. Assessment of the Accuracy of the MOBY Spectral Radiance Calibration Sources Using the SXR and the VXR
Published: 10/1/2000
Authors: Bettye C Johnson, Howard W Yoon, M Feinholz, D K Clark
Abstract: The Marine Optical Buoy (MOBY) and its related optical system the Marine Optical Sensor (MOS) consist of dual CCD-based spectrographs. MOBY, MOS, and other instruments operated by the MOBY team are used to provide in situ measurements of water-leavi ...

97. Radiometric Calibration History of MOBY/NIST Single Channel Dual Mode Radiometers
Published: 10/1/2000
Authors: Bettye C Johnson, Steven W Brown, Howard W Yoon
Abstract: In 1996, the National Institute of Standards and Technology (NIST), with the support of the National Atmospheric and Oceanic Administration (NOAA), designed and built two single channel, dual mode radiometers. The radiometers are used to assess the a ...

98. A Comparison of the Absolute Detector-Based Spectral Radiance Assignment with the Current NIST-Assigned Spectral Radiance of Tungsten Strip Lamps
Published: 9/1/2000
Authors: Howard W Yoon, Charles E Gibson
Abstract: Using a high-temperature blackbody (HTBB) and filter radiometers calibrated for absolute spectral power response, the spectral output of the blackbody, whose radiance temperature was determined using the filter radiometers, was used to assign spectra ...

99. Radiometric Calibration History of Visible and Near-Infrared Portable Radiometers
Published: 9/1/2000
Authors: Bettye C Johnson, Steven W Brown, Howard W Yoon
Abstract: The National Institute of Standards and Technology (NIST), with the support of the National Aeronautics and Space Administration (NASA), has built several transfer radiometers that are used in radiometric measurement comparisons to validate spectral- ...

100. Calibrated Thermal Microscopy of the Tool-Chip Interface in Machining
Published: 8/1/2000
Authors: Howard W Yoon, Matthew A. Davies, Timothy J Burns, Michael Kennedy
Abstract: A critical parameter in predicting tool wear during machining and in accurate computer simulations of machining is the spatially-resolved temperature at the tool-chip interface. We describe the development and the calibration of a nearly diffraction- ...
