Glossary
GL-9
IEC (825) Class 1 This is the lowest power IEC laser classification.
Conformity is ensured through a software restriction
of 120 seconds of laser operation within any 1000
second window and an automatic laser shutdown if
the scanner's oscillating mirror fails.
Intercharacter Gap The space between two adjacent bar code characters
in a discrete code.
Interleaved 2 of 5 A binary bar code symbology representing character
pairs in groups of five bars and five interleaved
spaces. Interleaving provides for greater information
density. The location of wide elements (bar/spaces)
within each group determines which characters are
encoded. This continuous code type uses no
intercharacter spaces. Only numeric (0 to 9) and
START/STOP characters may be encoded.
Interleaved Bar Code A bar code in which characters are paired together,
using bars to represent the first character and the
intervening spaces to represent the second.
LASER - Light Amplification by Stimulated
Emission of Radiation
The laser is an intense light source. Light from a laser
is all the same frequency, unlike the output of an
incandescent bulb. Laser light is typically coherent
and has a high energy density.
Laser Diode A gallium-arsenide semiconductor type of laser
connected to a power source to generate a laser beam.
This laser type is a compact source of coherent light.
Laser Scanner An optical bar code reading device using a coherent
laser light beam as its source of illumination.
LED Indicator A semiconductor diode (LED - Light Emitting
Diode) used as an indicator, often in digital displays.
The semiconductor uses applied voltage to produce
light of a certain frequency determined by the
semiconductor's particular chemical composition.
Matrix Symbols A 2-dimensional array of regular polygon shaped
cells where the center-to-center distance of adjacent
elements is uniform. The arrangement of the cells
represents data and/or symbology functions. Matrix
symbols may include recognition patterns that do not
follow the same rule as the other elements within the
symbol (i.e., Data Matrix and MaxiCode).
