The solution can be used under any assumptions of intensity distribution and phase aberration of the pumping wave.

In this paper,the phase distortion has been discussed,by using different reconstruction beam to reconstruct digital holographic image of 3D ob- ject in lensless Fourier holography.

A Lateral Shear Interferometer (LSI) is used for the measurement of the phase distortion of a laser beam propagating through the atmosphere, and for the detection of branch points.

The results of intensity distribution and phase distortion in second harmonic generation are presented when the fundamental wave are Gaussian beams with aberrations of Zernike polynomials,and the effects of different aberration,walkoff and diffraction are analyzed.

A nonlinear interferometric method for diagnosis of phase aberrance of a laser radiation and its second harmonic is described.
