Reconstruction of refraction angle topology from laser plasma interferogram

Summary form only given. A technique for reconstruction of the radial and axial components of the refraction angle as well as its module from an interferogram with visualization fields is discussed. In this approach the refraction angle is treated like a changing angle of a normal vector of the disturbed phase surface of the probing electromagnetic wave in comparison with its non-disturbed position. It is possible to reconstruct the phase surface of the probe beam from the interferogram.
