  The measuring system consists of laser, optic, controller, FFT module and software. A the HeNe laser, which is directly coupled with the optic (fp40 or fp50), is used for the basic system as light source. The advantage of this setup compared to fiberoptical solutions is high efficiency of the laser beam delivering and the low costs. The space-saving fiberoptical systems can be equipped with Argon Ion and Nd:YAG lasers.
The fiberopticalfp63 probe can be easily converted into a 2D-system by adding additional transmittingfibers. The coupling of the laser light into the fibers, the wavelength separation, and the frequency shifting is done within a fiber box.

 
 
  Probe fp40 with Controller
10mW HeNe-Laser, focal length f=90-160mm, no frequency shift, avalanche photodiode, velocity range v<40 m/s. Application : Calibration of flow sensors
     
  Probe fp80 with Controller
150mW Nd:YAG-Laser integrated in controller unit, also
available with Ar+-laser, one transmitting fiber(monomode, polarisation preserving), Braggcell and photomultiplier integrated in probe fp80, focal length f=310-500mm, velocityrange v<100m/s
     
  Probe fp63 with Fiberbox
Fiberprobe, focal length f=160-800mm, 2 transmitting fibers 1 receiving fiber, the 1D-probe can be upgraded to a 2D-system, watertight, fiberbox with Braggcell and dispersion   prism for wavelength separation, including high precision input manipulators, photomultiplier integrated in Controller
     
  Probe fp63 as a 3D-System
Designed for underwater applications, focal length in water f=600mm, tube for easy measuring volume adjustment
     
  Software
The evaluation of the doppler bursts by FFT methods is done with the well established PC based spectral analysis modules.Datarates of up to 1.8 kHz are achievable. The software contains a traversing module for positioning traversing units with up to three axes. An optional beam calculated module allows the determination of the
measuring points due to curved windows
