Appearance of wavefront dislocations under interference among beams with simple wavefronts

摘要

Abstract: The appearance of wave front dislocations underinterference among beams with simple wave fronts isconsidered. It is shown, that even two beams with thesmooth wave fonts is possible the formation ofdislocations screw type. The screw dislocations areformed in cross point of lines of equal amplitude ofbeams and minimum of an interference pattern. !7
