Full well capacity and dynamic range of CCD

AI Thread Summary
The discussion focuses on the full well capacity and dynamic range of CCD cameras, specifically how these values are determined. Questions are raised about whether full well capacity is calculated from pixel size or measured via saturation current, as well as the method for determining read noise. One contributor mentions that their company uses rule-of-thumb methods based on pixel size, clock phases, and electron density per micron squared of the substrate. This highlights the variability in measurement techniques across different contexts. Understanding these calculations is crucial for evaluating CCD camera performance.

Hi,

I have some question about the full well capacity and dynamic range of the CCD camera. The following link lists some full well capacity and dynamic ragnes of some CCD cameras:

My question is how they obtain the electron numbers of the "full well capacity e-" and "read noise e-". Do they calculate the full well capacity based on the size of the pixels, or they obtained the full well capacity by measuring the saturation current? How about the read noise? Thanks a lot.

I'm not sure about everything you ask, but one thing I do know is that in my company full well capacity is calculated using "rule fo thumb methods" based upon the size of the pixel, number of clock phases and average number of electrons per micron squared of your doped substrate (ie. buried channel).
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
