Photon Doppler Velocimetry, PDV

Photon Doppler Velocimetry (PDV) is a one-dimensional Fourier transform analysis of a heterodyne laser interferometry signal. It was developed at Lawrence Livermore National Laboratory. PDV is often used in the shock physics community as an adjunct or replacement for VISAR in the instrumentation of high-strain-rate events. Contemporary data acquisition technology and the availability of robust single-frequency lasers now leverage the assembly of these systems within reasonable budgets. Read more

Perimeter Security

The protection and security of critical assets such as power plants, airports, borders, and other kinds of infrastructures have never been more vital than today. The new distributed fiber optic sensor systems have better range and sensitivity than traditional sensor systems and can improve the security even further. Read more
