Portable X-Ray Systems for Use in Bomb Identification and Interdiction

December 1, 2007
Author(s)
Nicholas G. Paulter Jr.
The NIJ Standard for Portable X-Ray Systems is a minimum performance standard as applied to the man-portable battery-powered x-ray systems for use by bomb technicians and investigators. These systems comprise the x-ray generator, the image acquisition

Nanosecond Delay With Subpicosecond Uncertainty

September 1, 2007
Author(s)
Donald R. Larson, Nicholas Paulter
We have combined a commercially available, variable length coaxial delay line (trombone line) with a high resolution linear translation system. The result is better resolution and lower uncertainty in the achievable delays than previously available. The

Characterization of an Optical Time Domain Reflectometer Calibrator

March 1, 2007
Author(s)
Donald R. Larson, Nicholas G. Paulter Jr., Kenneth C. Blaney
We report the results of an investigation into the signal characteristics and behavior of an instrument used to calibrate Optical Time Domain Reflectometers. This instrument implements the Telecommunications Industry Association standard TIA/EIA-455-226

A Measurement of Propagation Delay

January 16, 2007
Author(s)
Donald R. Larson, Nicholas Paulter
A measurement method and associated uncertainty analysis have been developed for the measurement of propagation or group delay in electrical transmission lines and optical fibers. The measurement method and uncertainty analysis were applied to measurements

The OLES Imaging Metrology Program

November 22, 2006
Author(s)
Nicholas G. Paulter Jr.
The OLES Imaging Metrology Program is a broad-based interdisciplinary activity initiated and maintained for the development of metrology of digital imagery as applied to security, law enforcement, and corrections applications.

Impulse Spectrum Amplitude Uncertainty Analysis

October 1, 2006
Author(s)
Nicholas Paulter, Donald R. Larson
A detailed uncertainty analysis for an impulse spectrum amplitude measurement system is presented. This analysis includes consideration of effects such as temperature, computation algorithms, history of instrument performance, equipment limitations, and

Characterization and Calibration of an Optical Time Domain Reflectometer Calibrator

August 23, 2006
Author(s)
Donald R. Larson, Nicholas Paulter, Kenneth C. Blaney
We report the results of an investigation into the signal characteristics and behavior of an instrument used to calibrate Optical Time Domain Reflectometers. This instrument implements the Telecommunications Industry Association standard TIA/EIA-455-226

Characterization of an Optical Time Domain Reflectometer Calibrator

April 1, 2006
Author(s)
Donald R. Larson, Nicholas Paulter, Kenneth C. Blaney
We report the results of an investigation into the signal characteristics and behavior of an instrument used by the US Air Force Metrology and Calibration Program to calibrate optical time domain reflectometers. The instrument is calibrated using NIST

IEEE TC-10: Update 2006

April 1, 2006
Author(s)
Nicholas Paulter, W. B. Boyer, Thomas E. Linnenbrink, S. J. Tilden

Measurement of Impulse Spectrum Amplitude for Use in EMI Susceptibility Tests

March 1, 2006
Author(s)
Nicholas Paulter, Donald R. Larson
A system for measuring the impulse spectrum amplitude of the output of impulse generators and the response of receivers is described. The calibration procedures used in this measurement system were recently modified, which resulted in a reduction in the
