Description
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 alignment laser directly integrated on each output, all parameters adjustable on touchscreen…
