31. Radiometrically Deducing Aperture Sizes
Published: 2/1/2003
Authors: Allan W. Smith, Adriaan Carl Linus Carter, Steven Ray Lorentz, Timothy Michael Jung, Raju Vsnu Datla
Abstract: The desire for high-accuracy infrared sources suitable for low-background seeker/tracker calibrations pushes the limits of absolute cryogenic radiometry and blackbody design. It remains difficult to calibrate a blackbody at flux levels below 1 nW/cm ...

33. Combined Result and the Associated Uncertainty from Interlaboratory Evaluations Based on the ISO Guide
Published: 9/1/2002
Authors: Raghu N Kacker, Raju Vsnu Datla, Albert C Parr
Abstract: We address the problem of determining the combined result and the associated uncertainty in measurement of a common measurand by a set of competent laboratories. The issues include the following. What is the combined result and what uncertainty is a ...

Series: Special Publication (NIST SP)
Report Number: 980
Published: 4/24/2002
Authors: Gerome R. Reeve, Raju Vsnu Datla
Abstract: A short history of the relationship between the National Institute of Standards and Technology (NIST) and the Calibration Coordination Group (CCG) of the Department of Defense (DoD) from its inception in 1968 to the present is illustrated with descri ...

38. Diffraction Corrections in Radiometry: A Proposed Method to Estimate Uncertainties
Published: 1/1/2002
Authors: Eric L Shirley, Raghu N Kacker, Raju Vsnu Datla
Abstract: Radiometric determination of certain quantities, such as source radiance, geometrical aspects of an optical system (e.g., throughput, aperture areas and detector response relies heavily on the mathematical principles governing geometrical optics. Th ...

39. NIST Role in Radiometric Calibrations for Remote Sensing Programs at NASA, NOAA, DOE and DOD
Published: 7/1/2001
Authors: Albert C Parr, Raju Vsnu Datla
Abstract: The Optical Technology Division (OTD) at the National Institute of Standards and Technology (NIST) has been actively involved in providing calibration support to establish SI traceable measurement support for the NASA's Earth Observing System (EOS) r ...

40. Aspects of Practical Radiometry: Terminology, Uncertainty, and Physical Optics
Published: 1/1/2001
Authors: Eric L Shirley, Raju Vsnu Datla
Abstract: We discuss efforts that have been made to help establish-in practice-a greater uniformity of nomenclature used for various terms in radiometry as well as expression of measurement uncertainty. We also discuss the role of diffraction effects, which a ...
