Small-phase solution to the phase-retrieval problem

Not Accessible

Your library or personal account may give you access

Abstract

A solution to the phase-retrieval problem when the unknown phase is small is presented. The solution specifies the even and odd parts of the unknown phase in two separate equations. The odd part requires a single intensity measurement, and the even part requires two measurements. Phase diversity is used for the second measurement, and computer simulations are given.
