  • Blur & the PSF · Analyzing fluorescence microscopy

    Microscopy images normally look blurry because light originating from one point in the sample is not all detected at a single pixel: usually it is detected over several pixels and z-slices.This is not simply because we cannot use perfect lenses; rather, it is caused by a fundamental limit imposed by the nature of light. The end result is as if the light that we detect is redistributed slightly ...
