This highly compact miniLDV system is a great complement to FLOWCOACH where PIV & LDV can be utilized to provide students a complete understanding and demonstration of flow phenomena including turbulence measurements. The miniLDV System is an optional add on to FLOWCOACH. Simply attach the probe to the articulated arm in front of FLOWCOACH. The Burst Processor software collects data, moves the probe on the optional electronic traverses, and presents flow statistics such as flow velocities and turbulence. The process of measuring a profile is fully automated. The user simply dictates how many points per station to take, and the software does the rest. Please note that the Burst Processor software is not integrated into FLOWEX software.

The miniLDV System consists of: Optionally available are linear traversing systems (one or two axes) with manual or electronic drive (electronic traverses are controlled from within the software) and a computer with the software installed and verified by our technicians. The miniLDV probe is also available with an integrated Processing Engine as the Integrated miniLDV. 2D & 3D versions are also available. If the standard probes do not suit your needs, feel free to contact us and inquire about custom solutions.

*Class 3B LDV Laser Safety

Lasers of the Class 3B are considered potentially dangerous when a direct or specular reflective beam gets into the naked, unprotected eye (i.e. Direct glare into the beam).

Eye protection must be worn. LDV is a point measurement (i.e. only one very small point - in the order of microns - is illuminated by the laser).

The following precautions should be taken, to avoid a direct glare into the beam and to prevent an uncontrolled, specular reflection:

  1. The laser should only be operated in a monitored area.
  2. Unintended specula reflections should be avoided through extra care.
  3. Where possible, the laser beam should end its dedicated optical path on a diffusely scattered material. The colour and reflecting capacity of this material must allow beam alignment, and at the same time keep the dangers of reflection to a minimum.
  4. Eye protection is necessary even at the slightest possibility of a direct or specular reflective beam getting into the eye, or if there is a diffuse reflection that does not comply with (c).
  5. All accesses to the laser surveillance area need to be clearly marked with warning signs.
