Barcode Element Time Calculation
Realization of the full depth of field for all barcodes given in the specification is
based on the ability of the decoding hardware to resolve a varying range of
minimum element times. The minimum element time calculation for a given
barcode size at a given distance is shown in Equation 1(
below
).
Minimum Element Time = (Element Size / Spot Speed)
Equation 1.
Example:
Barcode Size = 5.2 mil
Spot Speed @ 95 mm from face = 650 inches/second
Minimum Element Time = (0.0052 inches/ (650 inches/second)) = 8.0 µsec
