A method extracting optical aperture synthesis observation objective Fourier information based on least squares is proposed. The theory is deduced. Compared with the other traditional methods, extracting interferogram fringes information based on least square requires much less time , and can extract observation objective Fourier modulus and phase together. Finally, a simulation about extracting interferogram fringes information is executed.
