Calibrating the camera
The calibration of the camera is performed as a non-uniformity correction (NUC). A NUC
is
an image correction carried out by the camera software to compensate for different
sensitivities of detector elements and other optical and geometrical disturbances

.
Calibration is needed whenever the output image becomes spatially noisy. This may, for
example, happen when the ambient temperature changes. The calibration can be carried
out automatically with different selectable intervals. It is also possible to perform a cali-
bration manually.
