The available parameters are the following: Figure 11-10 – Window “Rendering Parameters” "Sampling Distances”: these are the distances between the sections on axis X, Y or The value of these parameters is dependant on the scan time of the object being rebuilt.
  • Page 96 HiScan Touch Installation and Operation Manual OPTIKON 2000 Figure 11-11 – Scan results It is possible to use the axis Z adjustment function to correct the deformation of the 3D image (the length of the image is increased when the value of axis Z is increased or reduced).
  • Page 97 HiScan Touch Installation and Operation Manual OPTIKON 2000 This transformation should be performed for "experimental purposes only" and is recommended to avoid changing the original image. The available transformations are "Translation” and "Affine”: the first option compares adjacent frames in order to reduce the "noise" resulting from the probe translation...
