Laser PIV System for Educational Laboratory. Product Name
 
Laser PIV System Specification:
Laser PIV System (Code - T005006): Laser PIV System
Specification:

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 22° 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 laser’s 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
