Pulse Metrology, Part II

June 1, 2012
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
Pulse metrology refers to the science of the measurement of pulses, which are transient phenomena. This article describes concepts important for pulse metrology, namely, reproducibility and repeatability of measurement, measurement uncertainty, and

Objective Evaluation of Imager Performance

December 1, 2011
Author(s)
Francine K. Amon, Dennis D. Leber, Nicholas Paulter
We describe a method by which the evaluation and characterization of the performance of an imager can be done objectively and scientifically, that is, without routine operator interpretation. Although this method is demonstrated herein for passive long

IEEE TC-10: Update 2011

July 1, 2011
Author(s)
Nicholas G. Paulter Jr., Thomas E. Linnenbrink, W. B. Boyer, S. J. Tilden, Travis Ellis
There is a world-wide need to standardize terms, test methods, and the computation of performance parameters for devices that generate, measure, and analyze waveforms. Users need to be able to unambiguously specify the device performance required for

A High Resolution High-Sensitivity Standoff Imaging System at 350 GHz

May 23, 2011
Author(s)
Daniel T. Becker, Cale Gentry, James A. Beall, Hsiao-Mei Cho, William Duncan, Gene C. Hilton, Kent D. Irwin, Peter J. Lowell, Michael D. Niemack, Nicholas G. Paulter Jr., Carl D. Reintsema, Francis J. Schima, Robert E. Schwall, Peter Ade, Carole Tucker, Simon Dicker, Halpern Mark
Millimeter wavelength radiation holds promise for detection of security threats at a distance, including suicide bomb belts and maritime threats in poor weather conditions. The sensitivity provided by superconducting Transition-Edge-Sensor (TES) bolometers

A 350-GHz high-resolution high-sensitivity passive video imaging system

April 27, 2010
Author(s)
Daniel T. Becker, James A. Beall, Hsiao-Mei Cho, William Duncan, Kent D. Irwin, Gene C. Hilton, Robert D. Horansky, Peter J. Lowell, Michael D. Niemack, Nicholas G. Paulter Jr., Carl D. Reintsema, Francis J. Schima, Robert E. Schwall, Ki W. Yoon, Peter Ade, Carole Tucker, Simon Dicker, Mark Halpern
We are developing a 350 GHz cryogenic passive video imaging system. This demonstration system uses 800 photon-noise-limited superconducting transition edge sensor bolometers. It will image a 1 m x 1 m area at a standoff distance of 16 m to a resolution of

Calibration of Speed Enforcement Down-the-Road Radars

May 1, 2009
Author(s)
John R. Jendzurski, Nicholas G. Paulter Jr.
We examine the measurement uncertainty associated with different methods of calibrating the ubiquitous down-the-road (DTR) radar used in speed enforcement. These calibration methods include the use of audio frequency sources, tuning forks, a fifth wheel

Reference Ballistic Chronograph

April 30, 2009
Author(s)
Nicholas G. Paulter Jr., Donald R. Larson
A ballistic chronograph with a measurement uncertainty of less than +/- 0.1 m/s has been designed, constructed and tested. Because of this low uncertainty, this chronograph can be used as a reference to calibrate and/or characterize the performance of

Reference Ballistic Chronograph for Personal Armor Characterization

October 9, 2008
Author(s)
Nicholas Paulter, Donald R. Larson
Ballistic armor is evaluated using a V50 parameter, which describes the velocity above which half the shots are expected to penetrate a given type of body armor. The greater the error and uncertainty in measuring the velocity of the bullet, the greater the

IEEE TC-10: Update 2008

September 22, 2008
Author(s)
Nicholas G. Paulter Jr., Thomas E. Linnenbrink, W. B. Boyer, Robert Graham, S. J. Tilden
There is a world-wide need to standardize terms, test methods, and the computation of performance parameters for devices that generate, measure, and analyze waveforms. Users need to be able to unambiguously specify the device performance required for

Wide-Bandwidth Coaxial PWB Transmission Line Probe

April 1, 2008
Author(s)
Nicholas Paulter, Robert H. Palm, Dwight D. Barry
The design, fabrication, and test of a wide bandwidth (3 dB attenuation bandwidth =>30 GHz) , 50 ohm, coaxial probe for the electrical characterization of printed wiring board (PWB) transmission lines is described. The probe can make thousands of repeated
