If the scan rate is not important but the lateral resolution is the important
parameter, the shift of the scans may be reduced. This leads to more
“scans/profile” and consequently to a better lateral resolution with overlapping
spots and a reduced profile rate. This measurement mode is called “Fine Scan
Mode”.
•
Scan start direction: min. 45°
•
Scan angle: max. 90° with 4x1000 points interlaced.
•
Scan angle step: 90°/1000 points = 0.090° that will be interlaced
•
Scan Angle Shift: Each scan is shifted by 0.0225°.
•
Four scans can be interlaced to a single profile with 4000 points.
7.6.2 Taking Scans with the Terminal Mode
The Terminal Mode function “Take a scan” creates a table with the latest profile
scan. The ASCII format is "comma separated" and can easily imported to Excel or
Open Office.
1. Enter the Terminal Mode
2. Open in TeraTerm "File > Log...". Check "Plain text" and disable "Append"
3. Choose a log file name and close the dialog. Teraterm will now record all
sensor outputs.
4. Choose "S – Take a Scan"
5. Close TeraTerm
6. The log file can be opened directly with a common spread sheet program
like Excel or OpenOffice Calc.
