Optical optimization of the inversion of convolution products f = g * u when the unknown u is space-limited.

Abstract

For several convolution equations such as f = g * u, the support domain of the unknown being bounded, optical resolution becomes difficult as soon as f does not decrease quickly enough at infinity. When the approximation g(x - y) asymptotically equal to g(x) is good for |x| >> |Y|, we are able to correct by interferometric means the necessary truncation of… (More)
