1 Before you start
Scan patterns
single line
•
picket fence and ladder reading
•
set scan rate/position (scan width depends on reading distance)
•
picket fence—increase scan width to increase the number of scans
•
ladder—if possible, limit scan width to just over width of code in order to avoid
wasted scans
wasted scans
raster
•
picket fence only—do not use for ladder reading!
•
good for poor quality or damaged labels (read same code at different heights)
or variable label position
or variable label position
•
useful for multicode applications
•
set scan rate/sweep angle (scan area depends on reading distance and
sweep angle)
sweep angle)
•
if possible, limit raster or pattern to height of code in order to avoid wasted
scans
scans
lissajous curves
•
undefined orientation, curved surfaces
•
more directions = lower effective scan rate per line
multipattern sequence
•
for variable orientation and position
•
suitable for static reading or slow pass-through applications
•
cross pattern provides good coverage with codes with greater height than width
circle sweep
•
suitable for labels on circular surfaces, such as CD-ROMs or tires
