Thermal
The
Thermal
tab controls the function of the FLIR thermal imaging unit; this screen
will only have active functionality when the IR/Thermal tickbox in the
Standard
Controls
tab has been selected
Shutter Open/Close
The Shutter option provides manual control over the physical shutter of the imager.
Image Flip
Image Flip defines the orientation of the video output. As standard in the MIC 412,
this is
On
as the imager is mounted inverted inside the MIC.
FFC Mode and Settings
FFC stands for Flat Field Correction which is basically a refresh or recalibration of
the imager’s sensor. This process closes the shutter for about a second and at this
time the video will freeze with the previous image. When performing an FFC a
small green square will appear in the top corner of the video. This process can
clear any ghosting that may appear on the video output over time.
There are 2 different modes of operation,
Manual
where the
Perform Manual FFC
should be used as required, or
Auto
which will perform an FFC at the interval set in
seconds using
Set FFC Period
. By default this should be somewhere in the region
of 3 minutes.
Gain and Auto Gain Modes
The thermal imager has a number of different gain modes available dependant
upon the application. By default
Gain
will be on
Auto
and the
Auto Gain Control
Mode
will be
Histogram
.
Histogram
,
Linear
and
Logarithmic
modes are all fully
automatic modes which provide different scaling dependant upon the scene itself,
where the other modes require some user intervention, in the form of
Brightness
and
Contrast
settings which can be found under the
Manual Gain Controls
section.
This may be desired to get a perfectly exposed image in a fixed level environment.
For outdoor use it would be extremely difficult to specify manual settings that
would work well over the whole day and with changing conditions.
False Color
The thermal imager has 11 different false color options, which can highlight
different temperatures on a scene in different colors. The color range's are not
fixed and are dependant upon the gain settings of the imager, but for each specific
setting the colors will always remain in order of temperature from coldest up to
hottest over the scene. The Imager will remain in the False color mode selected
here after disconnecting Camset.
