The Dual Optical Embedded Dust Sensor (DOEDS) is designed for the sensitive, accurate detection of particles for preventive health monitoring of the AGT1500 engine and M1 Abrams/Ground Combat Vehicles (GCVs). DOEDS is a real-time sensor that uses an innovative combination of optical particle sensing technologies and mechanical packaging in a rugged, compact(More)
The signal improvement obtained for a spectroscopic measurement with a multipass cell can be expressed as the gain over a single pass measurement. We develop a unified analysis of amplitude gain and signal-to-noise ratio (SNR) gain for both cw and pulsed systems with application to Rayleigh/Raman spectroscopy, fluorescence, and similar techniques.
