Here, "3D" is not in the sense of Stereoscopy, which is a (subjective) optical effect. Fluorescence microscopy really registers three dimensional distributions. Default007 08:31, 30 January 2006 (UTC)[reply]

Diffraction

When will you see diffraction rings in a PSF and when will you not? In photography, bokeh generally doesn't show it but microscopy seems to. Does it appear when you approach the diffraction limit? Is it Fraunhofer diffraction or Fresnel diffraction? 155.212.242.34 (talk) 16:40, 7 December 2007 (UTC)[reply]

Mistake?

the image formation process is linear in power and described by linear system theory. This means that when two objects A and B are imaged simultaneously, the result is equal to the sum of the independently imaged objects. In other words: the imaging of A is unaffected by the imaging of B and vice versa, owing to the non-interacting property of photons.

Since photons have been scientifically been proven to interact, the explanatory conclusion is outdated. Thus, my question is: what has been attempted to be explained with the 'other words'?
