Video Signal
After launching
Video signal
the following page is displayed. The diagram displayed
in the large graph window on the right represents the video signal and the receiving row
in different states of post processing.
The video signal displayed in the graph window displays the spectral distribution of the
pixels in the receiving row. Left 0 % (small distance), and right 100 % (large distance).
The corresponding measured value is marked by a vertical line (peak marking).
The diagram starts automatically when the web page is loaded.

Video signal
web page
The
Video signal
web page includes the following features:
1 After clicking
Stop
data selection and zooming is still possible. Use the button
Save
to open the Windows dialog box for selecting the file name and location of
video signals resp. correction tables in order to save them as CSV file that contains
all pixels. Their (selected) intensities are output in % and further parameters.
2 In the window on the left, the video graph can be enabled or disabled both dur-
ing and after measuring. Inactive graphs are grey. Click on the check mark to add
them. If you want to have displayed one single signal, click on its name.
•
Raw signal (uncorrected CCD signal, red)
•
Dark corrected signal (raw signal minus dark level table, blue)
•
Light source corrected signal (signal which is corrected with the dark signal and
the light source table, green),
•
Dark value table (table generated in response to dark referencing, grey)
•
Light value table (table generated in response to light referencing, brown)
•
Recognition threshold , changeable (horizontal orange line)
•
Peak marking (vertical blue line), corresponds to the evaluated measured value
•
Linearized measuring range (limited by grey hatching), not changeable
•
Masked range (limited by pale blue hatching), changeable
Fields with a grey
background require a
selection.
Value
Fields with a dark
border require the
specification of a value.
