Stereo Assembly Model 640054

SKU:

The Model 640054 stereo assembly is to be used for Stereoscopic PIV configuration for 2D3C measurements.   The assembly provides all the parts to allow two cameras operated in the stereoscopic configuration for the 3-components of velocity measurement in a plane determined by the laser light sheet. 

Product Details

The stereo assembly includes the complete package of Scheimpflug mounts, stereo calibration target and rail to make the arrangement of stereoscopic PIV simple to operate.  The Scheimpflug mount, attached onto the camera between the camera body and the camera lens, provides the adjustment of the camera body to correct for any perspective distortion caused by the camera viewing the light sheet at an angle.  The correction is important to allow the camera capturing the seed particles illuminated by the laser light sheet clearly in focus and correctly, giving the correct 3-components of velocity result.

The Dual-Plane Dual-Sided (DPDS) calibration target used in the stereoscopic arrangement to provide an array of rectangular grid of dots to generate a mapping function for the correction of the varying magnification factor across the field of view illuminated by the planar laser light sheet. 

As for volumetric PIV system using four cameras, the single line arrangement requires all four cameras viewing the measurement volume at some angles with respect to the volume.  Hence the Scheimpflug mounts in this Stereo assembly can also be used with the four cameras to correct for the perspective distortion for those cameras.

Features & Benefits

  • Individual Scheimpflug mount used with each camera to correct for perspective distortion to give focused particle image across the entire field of view
  • Scheimpflug mounts can be used for all four cameras in volumetric PIV configuration
  • Dual-Plane Dual-Sided (DPDS) calibration target provides correct calibration of the perspective distortion without the needs to traverse the calibration target
  • Dual-Plane Dual-Sided (DPDS) target can also be used as calibration target for volumetric PIV with two cameras on each side of the target
  • Simple to set up and easy to operate
