Z-Trak2 3D Profiler Sensors
The dimensions of the machine opening required for setup are determined as follows:
H max = enclosure standoff di Z range
W min = Far FOV width
D = enclosure connector cable bend radius
The enclosure height, standoff distance, Z range, Far FOV width are AOI features, found in the
Data Output category in Z-Expert.
For a more detailed example of AOI features, see Depiction of AOI features.
Planning for unwanted light reflection or obstructed view
Acquiring quality profiles entails planning for unwanted laser light reflections or acquisition
blockages. The following examples depict a few potential issues to consider.
Blocked measurement area
Consider cases where the image sensor may not have complete visibility over the required scan
range. The scan direction may need to be reversed or the object may need to be scanned in two
opposite directions to fully inspect the object.
Figure 12. The form of the object blocks the image sensor.
Object shape obscuring some areas
Certain objects like the spherical example below create areas where the laser is blocked. Scanning
the object from two opposite directions in the Y-axis can form a more complete profile.
