Product Description

Specification of Laser PIV System

Laser

  • Solid-state air- cooled 200 mW, 660 nm laser diode (Class 3b).
  • Standard optics produce a c. 3 mm thick, 45° light sheet (c. 200 mm wide at 250 mm).
  • Interchangeable 20° light sheet optic available (item H41-3).
  • Pulse separation (t) of between 100 µs - 5 s (in steps of 10 µs).
  • Pulse width of between 10 µs - 32 ms (in steps of 10 µs).

Camera

  • Super-sensitive VGA CMOS sensor:
  • 640  480, 6.0 µm pixels (1/3 format);
  • ~50% quantum efficiency at 660 nm;
  • 75 - 110 dB dynamic range;
  • 4.8 V/lux·sec sensitivity.
  • Trigger input enables image pair acquisition to be synchronised with external events.
  • Accepts standard CS- or C-mount lenses (12.5mm f/1.4 lens supplied).
  • Camera exposure can be linked to the lasers pulsing, thereby enabling operation in a lit room.

Software Processing

  • Data refresh and recording rate up to 16Hz (dependent on the computer speed, the selected acquisition and PIV analysis parameters and the recording taking place)
  • Real-time, or offline, 2-component vector calculation.
  • Single pass or adaptive multi-pass cross-correlation with 8, 12, 16, 24, 32 or 64 pixel window sizes.
  • 0% or 50% window overlap (i.e. maps of up to 19,000 vectors).
  • Optional vector interpolation and filtering

Based On:

  • User-supplied velocity limits;
  • RMS of neighbouring vectors values.
  • Calculation of the following derived scalars:
  • Vector angle and magnitude;
  • Vorticity and swirl;
  • Time-averaged mean velocity;
  • RMS  and turbulence intensity.
  • Where  applicable, vector component and statistical sample number are user-defined.
