I see two in the first slide, and one in the second. In the latter, I do believe brighter light leads to more shot noise. I will leave the first two to the readers.
Yes, exactly, but someone looking at the signal will see the noise increase as the brightness increases, the opposite of what the slide says (assuming that there are enough bits to show anything at all).
The part on FWC needs revision. A bigger pixel does not automatically increase sensitivty and actually decreases SNR in low-light (also needs to be taken for dynamic range).
Too bad both of the posted slides have errors on them. I feel like a jerk saying this but we are talking engineering here.
ReplyDeleteHonestly, I did not have 2 hours to watch the videos, but just jumped back and forth to see few short parts. What are the errors that you find there?

Doesn't brighter light lead to more shot noise in absolute, but less in relative terms? (i.e. the SNR gets better)
