Measurement Science Enterprise, Inc. (MSE), located in Pasadena, California, manufactures mini and micro optical instrumentation used to measure flow speed, wall shear, and particle size and concentration for education, research, and industrial applications. The company consists of a core of scientists, senior engineers, and key consultants with extensive experience in optical instrumentation, experimental fluid mechanics, system design and engineering, and field campaigns.

Our Sensors

MSE manufactures standard and custom products based on three sensor methodologies (click on the appropriate link to find out more about how they work):

LDV/LDA: Laser Doppler Velocimeters (LDV), also commonly 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. MSE’s miniLDV and ultraLDV are the world’s most compact systems and are world-renown for their ease of use.

microPro: 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.

microS: The microS sensor, an MSE exclusive, is able to measure wall shear stress thanks to its unique holographic beam shaping technology which creates a diverging fan of laser beams from a single source.

microV: 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.

miniPCS: 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!
