      Detailed Specs

      Techniques like Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) are supported. LaVision’s FlowMaster PIV cameras can record two successive within min. time <100 ns for ultrafast cross-correlation and speeds up to Mach 4.

      • The PIV cameras offer highest sensitivity and allow the use of very small particles (or droplets).
      • An image field of up to 29 million pixels combined with up to 16 bit dynamic range gives an unsurpassed spatial resolution.
      • Programmable precise timing sequences in combination with flexible and speedy software evaluation complete the package.
      • Standard 2D-PIV (2D2C) measures two velocity components in a plane using a single CCD or sCMOS camera.
      • Stereo-PIV (2D3C) measures three velocity components in a plane using two cameras.
      • FlowMaster PIV systems can be used for 2D and stereoscopic flow field analysis.
      • FlowMaster 2D (2D2C) measure two velocity components in a plane with one camera.
      • FlowMaster Stereo-PIV (2D3C) is a straight forward extension of the FlowMaster 2D  concept and enables the measurement of all three velocity components inside a light  sheet using two cameras.
      • Stereoscopic PIV is based on the principle of stereoscopic imaging that is well known from the human eyesight.
      • Two cameras are image the illuminated flow particles from different angles.
      • Scheimpflug lens arrangements keep the planes in focus.
      • The combination of both camera projections allows the reconstruction of the “real” particle displacement inside the measurement area and evaluation of all three velocity components.
      • LaVision has developed new algorithms for an easier and quick calibration technique. The achieved self-calibration method is a unique tool to correct even large misalignments between calibration plate and laser light sheet. LaVision’s self-calibration method is a standard feature of the Stereo-PIV software in DaVis.
