Webb1 aug. 2002 · We investigate the propagation properties of partially coherent non-diffracting beams. They are obtained as a superposition of plane waves possessing a single radial frequency and interfering with controlled angular correlation. The theoretical model is adapted to the experiments based on the use of the Fourier spatial filter … Webb14 apr. 2024 · The shape of the obstacle can no longer be observed in the beam profile after a certain ...

Generation of arbitrary complex quasi-non- diffracting optical …
WebbThese can be readily engineered via modifica- tions of the angular spectrum of the beam in order to meet the requirements of particular applications. Such beams are not rigorously non- diffracting but they maintain their shape over large distances, which may be tuned by varying the width of the angular spectrum. WebbThese nondiffracting X waves can be almost exactly realized over a finite depth of field with finite apertures and by either broadband or bandlimited radiators. With a 25-mm diameter planar radiator, a zeroth-order broadband X wave will have about 2.5-mm lateral and 0.17-mm axial -6-dB beam widths with a -6-dB depth of field of about 171 mm. descargar need for speed most wanted 2016
