Demonstration of the technique of imaging with circular interference fringes

In this paper the frequency analysis is employed to investigate the image reconstruction process using circular interfering fringes. An experiment is used to demonstrate the reconstruction process and the reconstructed image of a twodimension object is reported. The technique of laser interferometric imaging takes advantage of the relative motion between the fringes（formed with laser） and the object to obtain the image information of the object. For the case of the laser interferometric imaging in which the circular fringes is adopted, it is often described with the principle of holography.
