Goldeye G/CL Technical Manual V4.1.1
Because each correction data set is applicable under certain conditions only, the
relevant conditions are stored with the data set.
An automated data set selection feature keeps track of the conditions. If any of the
parameters changes, the most suitable correction data set is selected
automatically. No additional user interaction is necessary.
Set to
Continuous
, this function updates the data set selection for every frame.
Background correction (BC)
The background correction is used as an additional correction, based on actual
operating conditions, to optimize the result of the NUC.
The correction data for the NUC is factory-provided and based on specific
conditions: exposure time, sensor temperature, and sensor gain setting. If the
conditions during camera operation are different, non-uniformity correction does
not work at best performance.
To compensate for remaining non-uniformity, the live image is corrected with a
previously recorded dark image. This image is subtracted from the precorrected
image to reduce the fixed pattern noise.
To adapt the BC to local conditions, customers acquire their own volatile correction
image. It is also possible to shift the offset individually, if needed.
Defect pixel correction (DPC)
The pixels of InGaAs sensors may show abnormal behavior in one or more of the
three characteristics:
•
dark offset
•
photo response
•
dynamic noise
