Abstract
The eigenvalues of the homogeneous Fredholm integral equation, whose kernel is a sin2 x/x2 function, are shown to be non-degenerate. An upper bound for the largest eigenvalue is established and an approximate formula for evaluating the eigenvalues is suggested. Applications of these results to speckle and photocounting statistics are presented.Keywords
