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 28.

= tilt angle

0° to

max

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 29 (the shaded zones are the NO

READ zones).
