Field of view diagrams
Take into account the following aspects in application design:
•
Field of view geometry of the device and position of the field of view in the space
in front of the device
•
Possible reading angles at which the codes can occur with respect to the device
•
For the planned working distance: resultant field of view length and width and min‐
imum possible resolution
