Chapter 10 Laser Control
MS-9 Scanner User’s Manual 10-5
Laser Off Time
Because scan widths are not always perfectly
symmetrical, the most effective way to setup
laser framing is to experiment with the Laser
On Time and Laser Off Time commands
until you get the best results.
The laser can be turned off between read
cycles and the duration of the scan and hence
the width of the scan can also be adjusted.
Figure 10-2 provides a visual representation
of how the laser beam width can be controlled
by the length of time the laser is on during
each scan.
When setting up Laser Framing in ESP, use
the Off Time and On Time arrows to con
-
strain or expand the laser framing area as
shown on
figure 10-2 on page 10-5.
Definition: Duration of laser off time, in increments of 1/500th of the total scan
width.
Important: The combined values of Laser Off Time and Laser On
Time cannot exceed 500 which is the duration of one scan.
