Abstract
Detection and evaluation of time- and space-domain fields scattered by one-dimensional objects is considered for applications in superresolved microscopy. Modal decomposition of scattered fields is used to estimate the information passed by band-limited diffraction from an object to the far field. The transinformation is shown to increase with the number of frequencies in the probe field.Keywords
