7 Basic Functions for Scan Head Control and Laser Control

1to1 Correction Tables
1to1 correction files
• Are not assigned to a particular scan system
• In general, serve test purposes only
• Alternatively, can be loaded by
load_correction_file with parameter
Name
= NULL.
– According to the further
Dim
parameter a 2D or
3D 1to1 correction table is being generated
internally.
Because some user programs require a file name and
do not accept NULL as the name, the
1to1 correction file
Cor_1to1.ct5
is supplied within
the RTC6 Software Package. This contains a
calibration factor of value 0. If a user program strictly
needs an “authentic” calibration factor, a
corresponding value can be specified with
CorrectionFileConverter.exe
, see Section ”Folder
CorrectionFileConverter”, page 32 (button Show File
Header > field ’Field Calibration [Bit/mm]’).
Inverse Tables
The ct5-correction file format supports “inverse
tables”. These are required for back transforming
actual scan head positions to the associated Image
Field coordinates.
For further information, see:
• Parameter 11, see page 179
• Chapter 8.1.3 ”Monitoring the Positioning”,
page 214
• Section ”Converting Correction Files”, page 180
