Reducing Uncertainty in Particle Size Measurement for Liquid Filter Testing

January 1, 2006
Author(s)
Barry M. Verdegan, Robert A. Fletcher
Contamination control is essential to reliable, cost-effective operation of hydraulic and engine systems. Particle counting provides the common, underlying basis for comparing filter performance and monitoring of contamination levels in hydraulic oil, lube

Nonlinearity of Response of Silicon Photodiodes at 193 nm

May 11, 2005
Author(s)
Shao Yang, Darryl A. Keenan, Marla L. Dowell
We have developed a measurement system based on a correlation method to characterize the nonlinearity response of silicon photodiodes to pulsed-laser radiation at 193 nm. The method compares the pulse response of the device under test with that of a

Optical Frequency Synthesis Based on Mode-Locked Lasers

October 1, 2001
Author(s)
Steven T. Cundiff, J Ye, John L. Hall
The synthesis of optical frequencies from the primary cesium microwave standard has traditionally been a difficult problem due to the large disparity in frequency, Recently this field has been dramatically advanced by the introduction and use of mode
