Abstract:

The availability of solid state lasers, and enabling MEMS (or MOEMS) technology, provide the opportunity to create novel optical sensors. In many cases this would not have been feasible with the use of standard fabrication techniques. In recent years, optical MEMS sensors have been developed to measure variety of parameters, including surface speed, flow velocity, skin friction, and particle and bubble sizing. Many non-intrusive flow measurement techniques require custom modifications in order to optimize for the special requirements.

Dr. Darius Modarress of Measurement Science Enterprise (MSE) Inc. will present information on miniaturized and integrated LDV (laser Doppler velocimeter), and other innovative micro-sensor systems, with probes capable of a wide range of measurement requirements. Applications such as near wall measurement, small and large volumetric flows, creeping flows and very high speed flows, high temperature, high humidity or high vibration environments will be presented. Information on the systems can be found at http://www.measurementsci.com/index.html.

The meeting will be held in MACLEOD 228. The presentation will describe the systems available and a demonstration of the miniLDV will follow.
