Polarization and Polarimetry

January 1, 2001
Author(s)
Kent B. Rochford
Definitions, descriptions, measurements, and models are presented for the optical properties of polarization and polarimetry. Included are the properties of birefringence, diattenuation, and retardance and the calculational methods of Jones and Mueller

Polymer-Clay Nanocomposite Materials: Solution and Bulk Properties

January 1, 2001
Author(s)
G Schmidt, A Nakatani, Paul Butler, V Ferreiro, Alamgir Karim, Charles C. Han
The influence of shear on viscoelastic polymer-clay solutions was investigated by means of small-angle neutron scattering (SANS) under shear. SANS measured the shear-induced orientation of polymer and platelets. With increasing shear rate an anisotropic

Precision Ultrasonic Wave Measurements with Simple Equipment

January 1, 2001
Author(s)
Steven E. Fick, C H. Palmer
We describe the design and construction of a relatively simple, inexpensive laser interferometer system for accurate measurements of ultrasonic waveforms in reasonably friendly environments. We show how analysis of a single waveform can provide both the
