measurement results that differ to those obtained with automatic exposure as
specified by ISO/IEC TR 29158. The manual setting can be useful if the automatic
system does not lead to a desirable setup or produces no decoding results. The
"Exposure duration" input field configures the manual exposure setting.
The measurement aperture can also be changed here. Typically, the aperture will be
left at the automatic setting. In this case, the aperture is set at 80% of the module
width. For all application specifications stored in the system, the aperture is used
according to the specifications (e.g. GS1 specifications or PPN specifications).
The aperture is specified using the unit "mil". The term "mil" means "milli-inches".
One inch equals 25.4 mm, and "milli" means 1/1000. Accordingly, 1 mil = 25.4 µm
(i.e. 0.0254 mm, since 1 mil is 25.4 mm divided by 1000). Typical apertures such as
6 mil or 10 mil correspond to 0.15 mm or 0.25 mm.
The measurement aperture imitates a spot of light as generated by a laser. Since it is
only a replica, the aperture is called a "synthetic aperture".
The synthetic aperture triggers image filtering functions that are intended to suppress
small, irrelevant faults in the code. Further details about the aperture can be found in
the REA training folder.
