Flat Panel Display Measurements and Standards

May 1, 1998
Author(s)
Edward F. Kelley
Display metrology is discussed as applied to flat panel displays (FPDs). Topics include the importance of properset up, expected measurement uncertainty vs. repeatability, and problems in making accurage light measurements. The role played by measurement

Infrared Spectroscopic Studies of Wind-Tunnel Contamination

May 1, 1998
Author(s)
Angela R. Hight Walker, David F. Plusquellic, Gerald T. Fraser, A Weber, Walter J. Lafferty
Three infrared diagnostic techniques are developed to characterize chemical contamination in wind tunnels and shock tubes which can affect the reliability of infrared sensor and imaging system tests. The techniques are based on mid-infrared spectroscopy

Kinetically-Controlled Chemical Sensing Using Micromachined Structures

May 1, 1998
Author(s)
Stephen Semancik, Richard E. Cavicchi
Microdevices produced by machining silicon can offer a variety of control functionality on a miniature scale, 1.2 with general advantages connected to not only reduced size (less invasive), but also lower power requirements, lower cost, and reproducibility

Model for Test Method Executive Control Committee (TMECC) Organization and Procedures Part of United States Geological Survey Recognition of Spatial Data Transfer Standard (SDTS) Topological Vector Profile (TVP) Certification System

May 1, 1998
Author(s)
W H. Dashiell, L A. Johnson, Lynne S. Rosenthal
This document describes an overview of the model for United States Geological Survey (USGS) recognition of private sector certification issuing organizations which provide conformance assessment for the SDTS/TV standard.

Nonlinear Ultrasonic Parameter in Quenched Martensitic Steels

May 1, 1998
Author(s)
Donna C. Hurley, Davor Balzar, P T. Purtscher, K W. Hollman
We have determined the nonlinear ultrasonic parameter Β and the ultrasonic longitudinal phase velocity {upsilion}L for a series of martensitic steel specimens which varied in carbon content.

Photon Physics Home Page

May 1, 1998
Author(s)
Uwe Arp, Charles S. Tarrio
The principal research activities of the Photon Physics Group are in the far ultraviolet and extreme ultraviolet [EUV] physics. In particular, we are currently pursing research activities in EUV optics, the development of x-ray microscopies, and

Physical Aging Behavior in Amorphous Pen Film as Measured by Creep

May 1, 1998
Author(s)
M L. Cerrada, G B. McKenna, J M. O'Reilly, J E. Greene, J R. Gillmor
Characterization of the viscoelastic and aging responses of poly [ethylene naphthalate] [PEN] is of increasing interest as this material begins to see greater use in commercial applications. In typical aging experiments, one quenches the glass transition

Process Specification Language: An Analysis of Existing Representations

May 1, 1998
Author(s)
Amy Knutilla, Craig I. Schlenoff, Steven R. Ray, Stephen T. Polyak, Austin Tate, S C. Cheah, Richard C. Anderson
The goal of the National Institute of Standards and Technology (NIST) Process Specification Language (PSL) project is to investigate and arrive at a neutral, unifying representation of process information to enable sharing of process data among
