The ATS600 also offers the following additional Profiles:
Patch Scans. Offers the ability to scan a small region around a selection of points.
Ring Scans. Offers the ability to scan in a full arc about the tracker.
Parameters used for these scans are defined in advance as part of a measurement profile definition. To do so, select one of the predefined profiles as the active measurement profile and press the View Selected Profile button to edit the profile settings.
The Patch Scan Cloud profile was added to facilitate auto-measure type operations where the reference points define the center of a patch of a give size. Selecting points from SA defines a collection of scan regions on the controller such that each point is scanned using a square patch.
A Patch Scan profile offers the following settings:
Accuracy. Set as Fast, Standard or Precise.
Separate Clouds. This check box determines if separate clouds will be used for different perimeters.
Patch Size. The patch size defines the size of the rectangular zone to be scanned. The entered value defines the length of one edge of the triangle. The opposing edge will be 10% larger.
Patch Angle. This angle defines the relative tilt of the patch from vertical
Max Distance. Defines a maximum limit such that data further than this threshold will not be recorded.
AOI Filter. The Angle Of Incidence (AOI) filter will exclude data recorded on a surface at a greater angle in degrees than the set value.
Signal Filter. This filter can be set to “Off, Low, Medium, and High” settings, and is based on a combination of broadening value and intensity.
From the Patch Scan profile window:
Select “Add Patch(es)-SA Pts” to select points from SA. Hit “Enter” to create the patches, and update the OVC if it is open.
Se the Patch Size as needed to define the size of the patch and edit the Patch Angle to adjust the scan direction (if helpful in applications like intensity target scanning).
Select “View Patches” to open the OVC to show your patches and control the region density, or to update the OVC with changed settings.
The patch size (length of square perimeter around each selected point, perpendicular to tracker line of sight) can be set here as well. Patches are shown in the OVC’s Regions tab. Point to Point spacing and Grow / Shrink Width is set there, like it is for Area Scans (both are per-region parameters).
Note - Any pre-existing Patch perimeters are cleared when creating new ones, unlike perimeters in an Area Scan, where new perimeters are added, and existing regions are not cleared.
Ring Scan definitions provide a means to measure a full arc about the tracker. This is accomplished using a Ring Scan Acquisition. This is the only profile that does not offer access to the OVC. The ring scan definitions are defined only using a Zenith angle (zero be- ing straight upward and 90 degree being straight outward from the tracker base) and a point / line spacing definition.
A Ring Scan profile offers the following settings:
Accuracy. Set as Fast, Standard or Precise.
Separate Clouds. This check box determines if separate clouds will be used for different perimeters.
Line to Line Distance. Defines the distance between line or arcs about the tracker.
Point to Point Distance. Defines the point spacing along a line or arc.
Min Zenith. Defines the lower limit in the vertical angular range covered by the arc recorded by the tracker.
Max Zenith. Defines the upper limit in the vertical angular range covered by the arc recorded by the tracker.
NOTE: You can move the tracker head to the desired position, and click directly in the profile grid on the Min Zenith and Max Zenith la- bels to make the tracker set these by measuring the vertical encoder of the tracker. The values are always in degrees. The current azimuth (horizontal angle) position of the tracker will not matter for this set- ting.
Min Distance. Defines a minimum limit such that data closer than this threshold will not be recorded.
Max Distance. Defines a maximum limit such that data further than this threshold will not be recorded.
NOTE: You can move the tracker head to the desired position, and click directly in the profile grid on the Min Distance and Max Distance labels to make the tracker set these by measuring the distance to the surface where it is pointing.
