What is a CDD Camera? - FreLon vs Pilatus Detectors

[poul]

Hey

I was wondering, is a CDD camera(e.g. FreLon detector) the same as an ordinary semiconductor detector (e.g. Pilatus detector). I have searched a little on the CDD camera, and for me it seems like the same thing. Wave Energy -> electron hole pairs -> signal.

Or have it something to do, with the way the signal is measured?

You probably mean a CCD camera with a CCD type of sensor in contrast with CMOS censors?

There is quite a bit of difference

Okay. As i understand it they are both semiconductor detectors, where the number of generated electron hole pairs says something about the signal.

I think i got some of it. In a CMOS the charge-to-voltage conversion takes place in each pixel. In a CCD each pixel’s charge packet is send to a common output structure, which converts the charge to a voltage.

Is this right?
