MSE specializes in miniaturized optical sensors with three universal characteristics: minimum size, minimum weight, and minimum power consumption. We offer a complete line of Laser Doppler Velocimetry systems with unequaled compactness and ease of use.
Laser Doppler Velocimeters (LDV), also referred to as Laser Doppler Anemometers (LDA), are interferometric sensors for measuring the velocity of fluids (gases or liquids) as well as solids (typically surfaces, though it’s possible to measure through—or into—transparent objects.
Unlike our competitors’, MSE’s probes are extremely easy to use because they do not require any complicated alignment after manufacturing and are the smallest, lightest, and lowest-power-consumption sensors currently available for optical speed measurement. All three sensor types can measure speed as well as direction, but each is tuned for a specific measurement distance.
The miniLDV and ultraLDV sensors are the world’s most compact systems and are world-renowned for their ease of use. The ultraLDV is designed for applications where sensitivity and precision are of utmost importance.
The microPro was designed specifically to fill a gap in boundary layer profilometry. The microPro probe contains a laser, miniature beam shaping optics, receiving optics, detection system, and an electronic traverse.
Throw away your Hot Wires! The 2D-LCA is an innovative anemometer for two-dimensional measurements of wind velocities at high spatial and temporal resolutions.
A miniPIV system is a great complement to the above sensors and offers a wide range of fields of view.
The microV is another MSE exclusive and is the smallest velocity sensor of its type. Using holographic beam shaping technology it is able to create two thin laser sheets from a single source and perform time-of-flight measurements of microscopic particles.
The microS sensor, which has since been discontinued, was able to measure wall shear stress thanks to its unique holographic beam shaping technology. This created a diverging fan of laser beams from a single source.
The miniPCS is a compact, self-contained system for the measurement of particle size. It has been used in many aerial field tests and can even tell when the coffee break occurred during a conference!
The miniPCS™ is a particle sizer/counter based on Mie scattering theory, able to measure particle size over a wide range. Its built-in acquisition electronics make it especially suitable for field tests.
The flowLab™ is a table-top-sized water tunnel, perfect for small research projects, expositions, and classroom demonstrations.
