Abstract

A phase reconstruction method using frequency-shifting is proposed. The frequency-shifting method is developed based on the properties of trigonometric functions. The computer simulation and the experimental result are also presented to demonstrate the feasibility and validity of the proposed approach in phase reconstruction.
