of laser operation within any 1000 second window and an

fails.
Intercharacter Gap
The space between two adjacent bar code characters in a
discrete code.
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.
Interleaved 2 of 5
A binary bar code symbology representing character pairs
in groups of five bars and five interleaved spaces. Interleav-
ing 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.
Laser
An acronym for Light Amplification by Stimulated Emis-
sion 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.
