Absolute optical ranging using low coherence interferometry

July 20, 1991
Author(s)
B. L. Danielson, C. Y. Boisrobert
We describe a method for measuring submicrometer distances with an asymmetric fiber Michelson interferometer having an LED as a source of radiation. By measuring the phase slope of the Fourier components in the frequency domain, it is possible to locate

Anomalies Observed in Wafer Level Microwave Testing

July 10, 1991
Author(s)
Dylan F. Williams, Roger Marks, T H. Miers, A Cangellaris
Two anomalies have been observed in the course of developing planar wafer level standards for the testing of GaAs monolithic microwave integrated circuits. The first involves a low-frequency characteristic impedance change of microstrip and coplanar

Assessment Methodology for the Fire Performance of School Bus Interior Components.

July 8, 1991
Author(s)
E Braun, J H. Klote, S Davis, Barbara C. Levin, Richard G. Gann, M Paabo
A full-scale fire performance protocol for the evaluation of school bus seat assemblies was developed. This protocol is based on the results of full-scale testing of end-use seat assemblies and computer fire modeling of the ignition source and burning item
