It has been a couple of weeks since my last post on the blog. I was a bit too busy and the combination with holidays slowed down the writing process. But now that the holidays have passed, I will try to make some time to start blogging again. After the almost endless series on the Photon Transfer Curve, it is time to start with soemthing new. The main topic of the new blogs will be HOW TO MEASURE … ? and you can replace the dots by any characteristic of the image sensor. Parameters of interest that will be discussed are going to be the dark current, dark non-uniformities, dark shading, etc, etc. This list is going to be also very long. The discussion of the measurements will be supported with data coming from artificial as well as from real images. Hopefully you as well as myself will learn from it. After all, that is the motivation to do this : sharing knowledge and improving our understanding of the imagers.
The first blog of this series that you can expect will be on the measurement of the average dark current will be discussed. It looks very straight forward, but there there a couple of interesting pitfalls. I am looking forward to it !!!
