83. Simultaneous Visible and Thermal Imaging of Metals During Machining
Published: 3/28/2005
Authors: Eric Paul Whitenton, Robert W Ivester, Howard W Yoon
Abstract: In order to investigate temperatures reached during orthogonal metal cutting, a novel approach for measuring temperatures at the tool-chip interface has been developed based on high-speed thermography. A thermal infrared camera and a visible camera ...

84. Spectral Radiance Comparisons of Two Blackbodies with Temperatures Determined Using Absolute Detectors and ITS-90 Techniques
Published: 9/1/2003
Authors: Howard W Yoon, Charles E Gibson, J L Gardner
Abstract: For calibrations of spectral irradiance standards, a high-temperature blackbody (HTBB) is used as a source of spectral radiance or irradiance as derived from Planck's radiance law. The temperature of such a blackbody can be determined using radiance ...

85. Spectral Radiance Comparisons of Two High-Temperature Blackbodies With Temperatures Determined Using Absolute Detectors and ITS-90 Techniques, ed. by D. Ripple
Published: 1/1/2003
Authors: Howard W Yoon, Charles E Gibson, J L Gardner

86. Spectral irradiance responsivity calibration of InSb radiometers using the improved IR-SIRCUS at NIST
Published: 10/15/2009
Authors: Jinan Zeng, Howard W Yoon, George P Eppeldauer, Leonard M Hanssen, Joseph Paul Rice
Abstract: The spectral irradiance responsivity calibrations of InSb radiometers measured on the tunable-laser based Infrared Spectral Irradiance and Radiance Responsivity Calibration with Uniform Sources (IR-SIRCUS) facility are discussed. This work describes ...

87. Spectroradiometric Characterization of the NIST Pulsed Solar Simulator
Published: 8/20/2009
Authors: Howard W Yoon, Brian P Dougherty, Vladimir Khromchenko
Abstract: The spectroradiometric characterization of the NIST indoor pulsed solar simulator is described. The solar simulator has a flash duration of 36.4 ms and is designed for solar panels having a maximum size of 2.0 m by 1.6 m. As per industry standards, ...

88. Spectroradiometric Sources
Published: Date unknown
Authors: Howard W Yoon, Charles E Gibson
Abstract: rth climate modeling and global impacts of particles and gases in the atmosphere are some of the studies that benefit from the use of spectroradiometers calibrated for spectral irradiance. Spectral irradiance is the optical power incident per unit ...

89. Standardization of UV LED measurements
Published: 9/8/2015
Authors: George P Eppeldauer, Thomas C Larason, Howard W Yoon
Abstract: Traditionally used source spectral-distribution or detector spectral-response based standards cannot be applied for accurate UV LED measurements. Since the CIE standardized rectangular-shape spectral response function for UV measurements cannot be re ...

90. Summary of NIST Short Courses offered by the Optical Technology Division
Published: 1/1/2005
Authors: Carl C Miller, Howard W Yoon, Bettye C Johnson, Yoshihiro Ohno
