Title :
Signal power in heterodyne detection as a function of the number of airy rings on the detector
Author :
Cathey, W.T., Jr.
Abstract :
Integration of a heterodyne signal over the detector area gives a variation in total signal intensity as a function of relative size of the Airy pattern which differs considerably from the fraction of total energy within circles of prescribed radii in the Airy pattern.
