Recent Advancement of Laser Velocimetry

Laser Doppler Velocimetry

Thermographic laser Doppler velocimetry.

We propose a point measurement technique for simultaneous gas temperature and velocity measurement based on thermographic phosphor particles dispersed in the fluid. The flow velocity is determined from the frequency of light scattered by BaMgAl10O17:Eu2+ phosphor particles traversing the fringes like in conventional laser Doppler velocimetry. Flow temperatures are derived using a two-color rati...

Recent Advancement of MMP Inhibitors

Volume 4 • Issue 2 • 1000e112 Adv Tech Biol Med ISSN: 2379-1764 ATBM, an open access journal Matrix metalloproteinase (MMPs) are a family of zinc dependent endopeptidases that play a significant role in cancer as well as in numerous other diseases [1]. It degrades the extracellular matrix (ECM) components and controlled remodeling of ECM is essential for invasion, metastasis and growth of vario...

Laser Doppler velocimetry of basilar membrane vibration.

A method is described for the measurement of basilar membrane (BM) vibration velocimeter (LDV). The instrumentation was coupled to a compound microscope which served to visualize reflective glass microbeads placed on the BM. The laser beam of the LDV was focused in the microscope object plane and positioned over the reflective bead. We show examples of frequency tuning curves and displacement i...

Recent Advances in Micro-Particle Image Velocimetry

Microfluidic devices are becoming increasingly common and are seen in applications ranging from biology to nanotechnology and manufacturing. Flow behavior in these small domains can often be counterintuitive because of the low Reynolds number or the relative importance of surface forces. Microparticle image velocimetry (μPIV) is a quantitative method that can be used to characterize the perform...
