2315NDT v2 CMOS X-ray Detector User Manual

•

Auto-descramble

•

Dark correction

•

Gain correction

•

Defect correction

2

Place a phantom or a test object on the detector surface, within the FoV

3

With the X-ray beam on, capture a single image by clicking

Snap

.

4

The result should be a clean-looking image with no obvious background shading, striping,

artifacts, or lines, as shown in

.

Figure 5

Sample Image

Note

If the detector is moved or other X-ray parameters are needed, the calibra-
tion must be performed again.

Note

It is important that the detector is not moved once calibrated and that the
exact same X-ray parameters used for the Flood field correction are used for
the final corrected X-ray image.
