We discuss how we can obtain noniteratively an exact solution for the modified normal equation in least-squares phase estimation from the measured phase difference. To achieve this, we introduce the idea of equivalent transformation of the measured phase difference into a periodic one. ... Hiroaki Takajo and Tohru Takahashi...
