Taking Scans
7.6.1
Setting up the Scan mode
With each of the scan modes, the following measurement parameters are set:
•
Scan rate: Number of scans per second.
•
Scan start direction: direction of the first measurement point of a scan.
•
Scan angle: size of the scan area in degree.
•
Scan angle step: small angle between two subsequent measurement points.
Defined by the scan angle size and the number of measurement points.
•
Scan Angle Shift: small angle between the start directions of subsequent scans.
The scan mod can be set with the user parameter:
Scan mode: 0=off, 1=normal, 2=fast, 3=fine, 4=reserved
Normal scan mode

Normal scan mode
The „Normal Scan Mode” is defined by the following parameters:
•
Scan start direction: min. 45°
•
Scan angle: max. 90° with 1000 points.
•
Scan angle step: 90°/1000 points = 0.090°
•
Scan Angle Shift: Normal-Mode scans are not shifted.
Fast scan mode

For increasing the scan rate the point density has to be reduced. In „Fast Scan
Mode” the point density is halved, the scan rate is doubled and the “profile rate”
reduced accordingly.
•
Scan start direction: min. 45°
•
Scan angle: max. 90° with 500 points.
•
Scan angle step: 90°/500 points = 0.180°
•
Scan Angle Shift: Fast-Mode scans are not shifted.
