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.
| Laser Beam |
| 0° to α max |
α | α = tilt angle |
| 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).
