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 (

maximum) under which the code

reconstruction process is still possible.

We define the Tilt angle as the angle (

) between the laser beam and a line

parallel to the barcode label, as shown in Figure 3.3.

Laser Beam

= tilt an

0° to

max

Figure 3.3 - Tilt angle

The formulas to calculate

maximum depend on various parameters such

as: label height, number of scans per second, code motion speed, etc. To

obtain

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 +

max and -

max as shown in Figure 3.4 (the shaded

zones are the NO READ zones).
