Let's make a list of things that affect the sparkle. Brightness of the light source. Contrast with the background. Visual size of the light source. Size of the ripple on reflecting surface. Angle of reflection doesn't seem to affect much, since the sparkling effect can be seen in both low and high angles. The effects from pixel size of the sensor is yet to be determined.
This is so tedious, I'm out.

Reply 180 at least moves towards a definition of sparkling, though whether the visual effect is due to saturation of the sensor, scatter in the sensor, or flare in the lens assembly, is not clear.
It seems like you have never starred at sparkling water surface.
Some sparkling dots in the short video last much longer than a frame duration.
Do you understand detector saturation?
Quote from: Bored chemist on 09/10/2023 12:03:25Do you understand detector saturation?Yes. That's what you should say, instead of scan rate.

That's what you should say, instead of scan rate.I didn't say scan rate.Perhaps you should "cut to the chase" and tell us how sparkles on the water would look without "quantisation".
Is the attosecond laser quantized?
The 2023 Nobel Prize for Physics was awarded to a fantastic trio working towards imaging electrons on the attosecond scale. I am an optical physicist, so I naturally want to take a deeper look at why this discovery is important, how it actually works, and what it unlocks for our understanding of the universe around us and how it actually behaves. 0:00 Electrons and the world of the minute.1:22 "Everything in physics starts with Einstein" - Isaac Newton2:26 Breaking the 6 femtosecond record5:27 How to build the world's fastest laser pulses7:05 Ad read7:50 How to see an Electron9:03 Why don't you just use a single photon?
