Photonic Doppler Velocimeter - Non Contact Laser Measurement 0 - 20km/s
OVERVIEW
Photonic Doppler Velocimeter : for more reliable measurement on your high speed phenomena
IDIL Fibres Optiques developed the first industrial Photonic Doppler Velocimeter for shocks and detonic applications. This technology allows to measure unique or multiple speeds, in the range of 0 to 20 km/s with an excellent temporal resolution. A dedicated software, based on a Fourier Transform algorithm, allows a rapid visualization of the speed fields. With a 5U height, the compact and modular system allows the user to build its PDV system from 1 to 4 measurement channels.
This new system integrates some improvement such as : low velocity measurement option with a fixed shift frequency, red alignement laser directly integrated on each output, all parameters adjustable on touchscreen…
