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. |

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 |
