Abstract

We have been Concerned to ascertain just how well our understanding of white light speckle phenomenology matched the quantitative aspects of white light speckle imagery. For reasons of simplicity we have restricted our attention principally to the Labeyrie signal amplitude and the Knox-Thompson phasor per se, and to the image derivable there from. For this purpose we have processed in various ways two sets of short exposure, narrow spectral band "images." Each image is photodetection event shot noise limited in the sense that the image consists simply of the coordinates locating each of some random number of photodetection events. One set of short exposure "images" corresponded to the single star ζ-Delphinus, the other set to the binary star β-Delphinus.
