Bill-W,
Whilst I totally agree with your comments on these images, there is a little more to this story. The OP has managed to rebuild a working thermal camera using two faulty units, an SC640 and a P640. I am in communication with the OP via messaging but it will be far better to use this thread to help him.
My issue with the provided images is that these appear atypical of a SC6xx or P6xx camera as the column noise seems excessive in the example images. The SC6xx and P6xx are high performance imaging systems so something is not right here. My PM series cameras are older and less capable, yet do not display this column noise issue. Such is normally dealt with in the image processor sub system. I have asked the OP to detail exactly what parts were combined from the two cameras to create a working unit. We could be seeing either an issue in the video processor sub system or a calibration (NUC) issue. I would have expected dead pixels to appear if the wrong Calibration tables were in use though. It is a bit of a mystery to me at the moment.
If I saw a SC6xx producing these images when new, I would reject it as unacceptable column noise and a non uniform image response.
It is almost as though the cameras normally excellent image processing is not active
As we know, you have to be careful when transplanting PCB’s in these multi PCB cameras. Some do not play well together if mismatched. FLIR also program each PCB’s serial number into both the PCB subsystems and LiCO main controller. I would expect an error to pop up if the serial number mismatch was a problem though. When FLIR replace PCB’s in these cameras they also carry out a fresh calibration run to ensure all PCB’s work well together.
