Not a dumb question and sorry I missed this 4 months ago. If the dark current is constant then obviously it is just linear with integration time. If it is non-linear, e.g. dependent on ...

The link now shows the June 2022 publication date, volume, issue no., and pages.

If I get the chance I will try to write something down, but I suppose there are several people here, at least, that can explain depletion on a semiconductor. Quick - it is when all the mobile ...
-
"Charging up" the FD voltage is depleting the sense diode. And then there is the PPD which also starts out fully depleted. No problem with the bucket analogy. Sorry. EF

Row-wise temporal noise will appear "frozen" in a single still image. In a 2nd image, the temporal noise will be manifested differently, by definition. Thus the well known methods of FPN ...

The right side image was taken with an off-the shelf camera that uses the best-in-class commercial sensor from a well known high quality sensor manufacturer. I can't tell you what the camera ...
-
i am sorry but I don't know. I would guess close to 1e- mean signal but it is just a guess. Well, at 1e- avg signal, the shot noise is already 1e- rms. So not obvious that one needs read noise a ...
-
Thanks Jack. -I have not heard of commercial CIS with read noise under 1e- yet but if it hasn't happened yet, I guess it will soon. I think many of us in the image sensor technologist space were ...

For the hardcore among us: As mentioned 3 weeks or so back, this review paper has now become available for those interested. It is open access from IEEE, and also "early access" which means it has ...

The pleasure is always mine! Eric

I thought the Phase One XT was about 150Mpixels? True? In fact, it is DPR's reference camera: ...

Thanks again John. As they say, he who laughs last... If you ever find a copy of that discussion, please let me know. I'd be interested in reading it. Probably it has gone the way of ashes to ...
-
Probably dozens of things that could cause a color shift or light shading related to the image sensor. Would any of them be noticeable to your naked eye? Not likely in a commercial product. You ...
-
Thank you John. I assume by 1-bit digital imaging you meant a binary sensor, where a "1" corresponds to some threshold of signal, not necessarily a single photoelectron. And in our case, the 1 ...

Gigajot announced a larger photon-counting image sensor . While I am not involved day to day with Gigajot, it spun out of my lab at Dartmouth to commercialize the quanta image sensor (QIS) ...
-
Not really correct. Sensor technologists, like optical technologists, work hard to remove both systematic non-uniformities, such as those caused by resistive connections to pixels, and RC delays ...

near future - not likely imo Not really the major factor. It is more related to pixel size. Put a 1um pixel in mirrorless or DSLR camera and you will find it is 3D stacked BSI CIS. Again, just my ...
-
I think the only thing we both did was simplify things to the concept of a blur-disk. The Airy disk is in fact more like a Gaussian and the bad blur area is a smaller diameter than the Airy disk ...

For non-silicon materials usually the "rub" comes from lag and read noise. Certainly a technology to keep an eye on. On the other hand, single crystal silicon sensors are working their way down ...
