Diffraction limit deconvolution

Figure 3.20 A schematic idea for an imaging IR microspectrometer system using the synchrotron source and FPA detector. The FPA detector serves to spatially oversample a diffraction-limited region of the specimen for subsequent PSF deconvolution and resolution enhancement.

Deconvolution methods, such as the one described previously, provide an effective means for studying objects that have simple geometries, such as single stars whose diameters are resolved or binary star systems describ-able only by the angular spacing of the two components and their relative orientatiom However, for more complex objects, it is necessary that actual images of these objects with diffraction-limited detail be reconstructed from the speckle data. A fundamental problem in such... 

The radial distribution functions of liquids are experimentally accessible through neutron diffraction studies [7] Fig. 9.3 shows the scattered intensity from liquid deuterated benzene. The information carried by such diffraction profiles is limited, but is sufficient for deriving some important structural conclusions, like the presence and nature of stable dimers in the liquid state. Some principles of this experiment can be gathered from a consideration of the examples in Section 5.8, but in practice, especially for complex molecules or liquid solutions, the details of the structure determination are demanding and require a complex deconvolution of the pair contributions...
