Scaling Sensitivity of Focused Laser Differential Interferometry Across Facilities
Focused Laser Differential Interferometry (FLDI) is a novel technique that leverages opticalinterference to measure density fluctuations within high-speed fluids. This technique provides excellent spatial and temporal resolution compared to traditional measurement techniques by offering a …

Application of optical fibers to wideband differential interferometry and measurements of pulsed waves in liquids
Wideband differential interferometry has been applied to the detection of SAW on specimen surfaces and ultrasonic compressional waves in liquids. Herein is described the performance of a wideband differential system which uses single mode optical fibers to transmit coherent light from input optics …

Imbedded optical fiber sensor of differential strain and temperature in graphite/epoxy composites
… in graphite-epoxy composite materials using differential interferometry is described. The sensor uses two single-mode optical fiber waveguides imbedded within the composite during prepreg ply lay-up. Strain and temperature changes arc obtained as a motion of an optical interference pattern. …

Interface Driven Dynamics at Nanoscales:Polymer thin films and Electrical Double Layer
The electrical double layer (EDL) is formed due to the accumulation of charge at the interface of a metal surface in contact with an electrolyte. The total charge in the EDL compensates the charge on the metal surface. As EDL is the layer that "connects" the electrode to the "bulk", all electrode …
