Caledonian: couldn’t you always do better in such a case, in principle (ignoring resource limits), by increasing resolution?
I double-checked the concept of ‘optical resolution’ on Wikipedia.Resolution is (roughly speaking) the ability to distinguish two dots that are close-together as different—the closer the dots can be and still distinguished, the higher the resolution, and the greater detail that can be perceived.
I think perhaps you mean ‘sensitivity’. It’s the ability to detect weak signals close to perceptual threshold that noise improves, not the detail.
