In March 2002 NIST became the lead agency in an investigation of the World Trade Center collapse. The investigation addresses many aspects of the catastrophe...
Nanoindentation of single crystals has been a topic of recent investigations. This is a result of their ability to withstand near theoretical stresses without...
This webpage is really a series of webpages all linked together by an index which ought to be self-explanatory. Most of the items are just administrative in...
A miniature Fourier transform spectrometer (MFTS) has been tested as a device for remotely measuring the temperature of a high-stability/emissivity blackbody...
A graphical user interface computer program based on a Windows95 API platform has been written in the C programming language to aid in the rotational analysis...
The National Aeronautical and Spece Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), the Department of Defense (DOD), the...
Temperatures within semiconductor processing plasmas are important since they control the various reaction rates of the plasma and consequentially can...
This package contains the documentation for a program that computes diffraction corrections for simple radiometric applications. A diskette containing the...
In a companion presentation, a procedure is described for in situ calibration of a radiation thermometer (RT) with a standard uncertainty of 2.1 degrees C in...
Imaging trying to make temprature measurements in a spatial region equal to the edge of a printer paper or within the diameter of a strand of hair. The accurate...
Recently, there have been significant advances in measuring and controlling the phase of ultrashort optical pulses. These developments have begun to blur the...
Our current spectral radiance and irradiance scales are derived from the radiance temperature determination of a blackbody at the freezing point of gold (GPBB)...
The characteristics and performances of the NIST High Purity Germanium (HPGe), Sodium Iodide (NaI(Tl)) and Cadmium Telluride (CdTe) gamma-ray detectors were...
Researchers in the Optical Technology Division utilize measurements of radiant flux to determine temperature. This includes the dissemination of the ITS-90...
