5.5 Setting the Emissivity
There are the following ways to set the emissivity:
•
Setting the emissivity of sector 0, the “sector” for the digital interface.
•
Setting the emissivity of sector 1 … 3, the sectors for the analog interface.
•
Setting the emissivity for each pixel with an emissivity vector (command
EMV
).
•
Setting the emissivity using the voltage input of the scanner (commands
ESrc, ERange
)
The emissivities are handled with the following priorities:
•
The emissivity of sector 0 gets overwritten by the emissivities of sector 1...3.
•
If the emissivity vector is used all sector emissivities are overwritten by that vector.
•
If the voltage input is configured as emissivity source, then the value calculated out of the
voltage input (using
ERange
) overwrites all others above.
5.5.1 The Emissivity Vector (
EMV
)
It is possible to give every pixel its own emissivity, using the command
EMV
.
The syntax of this command differs a little from all other commands to allow its handling with a
terminal program too.
The vector is given with:
EMV <emissivitiesVector>
.
wherein
<emissivitiesVector>
gives the 1024 emissivities (or at least as much as are used,
corresponding to the count of pixels) as floating-point numbers.
(Example:
EMV 0.1 0.304 ... 1.0
)
It is possible to set all emissivities to one value:
EMV all <emissivity>
.
(Example:
EMV all 0.95
)
The use of the emissivity vector can be switched off by:
EMV off
.
To get the emissivity vector the command
GEMV
is used. It adds newline- and return-characters to the
numbers to achieve a better reading in a terminal.
With:
GEMV actual
the currently used emissivities are shown. This allows to check the priorities of
the concurrent methods to set the emissivity.
