3.1.1 Tilt Angle for Advanced Code Reconstruction
The most important parameter in Advanced Code Reconstruction is the
value of the maximum tilt angle (
α
maximum) under which the code
reconstruction process is still possible.
We define the Tilt angle as the angle (
α
) between the laser beam and a line
parallel to the barcode label, as shown in Figure 3.3.

Figure 3.3 - Tilt angle
The formulas to calculate
α
maximum depend on various parameters such
as: label height, number of scans per second, code motion speed, etc. To
obtain
α
maximum for your application, please contact your Datalogic
representative.
You must remember that the decoder will be able to read the label with a tilt
angle between +
α
max and -
α
max as shown in Figure 3.4 (the shaded
zones are the NO READ zones).
