Vertical Scanning Technology
Vertical Scanning Principle
• the Piezo lifts the objective in z axis and the camera the grabs images in equidistant steps
• the image stack contains the information to calculate the profile data from the surface
• each independent pixel will show an so named correlogram an the maximum sinus like light variation
indicates an defined z-distance from the objective
