Optical Properties of Materials: A Sampling of NIST Contributions

January 1, 2000
Author(s)
Thomas A. Germer, R Gupta, Leonard M. Hanssen, Eric L. Shirley
Optics has found an extremely wide range of applications in industry and science, and the properties of the materials that make up optical instruments are key to their performance. Examples include glass for optical instrumentation such as telescopes and

Parameter Selection for Constrained Solutions to III-Posed Problems

January 1, 2000
Author(s)
Bert W. Rust
Many physical measurements are modeled by linear integral equations expressing each measurement as the sum of an instrumental smearing of the desired function and a random measuring error. Discretizing the integrals gives an ill-conditioned linear

PARCS - A Primary Atomic Reference Clock in Space

January 1, 2000

Thomas P. Heavner, Leo W. Hollberg, Steven R. Jefferts, D Meekhof, Thomas E. Parker, William D. Phillips, S L. Rolston, Neil Ashby, W Klipstein, L Maleki, D Seidel, R W. Thompson, L Young, R Vessot, E Mattison, A Demarchi

Performance Evaluation of a Parallel Cantilever Biaxial Micropositioning Stage

January 1, 2000
Author(s)
E Amatucci, Nicholas Dagalakis, John A. Kramar, Fredric Scire
The phenomenal growth of opto-electronic manufacturing and future applications in micro and nano manufacturing has raised the need for low-cost high performance micro-positioners. The National Institutes of Standards and Technology (NIST) Advanced

Phase Radiography with Neutrons

January 1, 2000
Author(s)
B E. Allman, P J. McMahon, K A. Nugent, D Paganin, David L. Jacobson, Muhammad D. Arif, S. A. Werner

Polymer Layered Silicate Nanocomposites: Thermal Stability of Organic Cationic Treatments

January 1, 2000
Author(s)
Jeffrey W. Gilman, A B. Morgan, Richard H. Harris Jr., Paul C. Trulove, H DeLong, T E. Sutto
Nanocomposites result from the combination of materials with different properties at the nanometer scale. Some examples of these include: polymers combined with layered-silicate, polymers combined with nano-silica, hybrid materials prepared by sol-gel
