55. Advances in Radiometry for Ocean Color
Published: 11/10/2003
Authors: Steven W Brown, D K Clark, Bettye C Johnson, Howard W Yoon, Keith R Lykke, S Flora, M Feinholz, N Souaidia, C Pietras, Thomas C Stone, M Yarbrough, Y S Kim, R Barnes, J Mueller
Abstract: Organic materials in the oceans have spectral signatures based on their light-scattering properties. These optical properties are related to bio-physical and bio-chemical data products, such as the concentration of phytoplankton chlorophyll-{alpha} ...

56. Thermal Imaging of Metals in a Kolsky-Bar Apparatus
Published: 10/1/2003
Authors: Howard W Yoon, D Basak, Richard L. Rhorer, Eric Paul Whitenton, Timothy J Burns, Richard Joel Fields, Lyle E Levine
Abstract: For materials testing at elevated temperatures, we describe the design and the development of a resistively heated Kolsky-bar apparatus. The temperature of the sample is determined by non-contact thermometry and the spatial temperature gradients in ...

57. 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 ...

58. The Development and Characterization of an Absolute Pyrometer Calibrated for Radiance Responsivity
Published: 9/1/2003
Authors: David W Allen, Robert D. Saunders, Bettye C Johnson, Charles E Gibson, Howard W Yoon
Abstract: The International Temperature Scale of 1990 (ITS-90), for temperatures above the freezing temperature of silver, is defined with pyrometers which rely upon spectral radiance ratios to one of the silver, gold or copper freezing temperature blackbodies ...

59. A Method for Testing the Spectral Responsivity of Infrared Cameras Using Tunable Lasers
Published: 8/1/2003
Authors: Joseph Paul Rice, Keith R Lykke, Howard W Yoon
Abstract: We are developing a technique for accurately measuring spectral responsivity functions of infrared cameras using tunable lasers. We present preliminary results for uniform scenes where tunable infrared lasers illuminate an integrating sphere, diffus ...

60. Kolsky Bar With Electrical Pulse Heating of the Sample
Published: 6/1/2003
Authors: Eric Paul Whitenton, Michael Kennedy, Matthew A. Davies, Gerald V. Blessing, Brian S. Dutterer, Richard L. Rhorer, Howard W Yoon, Lyle E Levine, Richard Joel Fields, D Basak, Timothy J Burns
Abstract: The accuracy of simulations for modeling of machining processes is often limited due to insufficient knowledge of the material properties during machining, which can involve strain rates on the order of 104 per second or higher, plus rapid material h ...
