WebSep 1, 2024 · The abscissa is the position coordinate of the light field, and the ordinate is the incoherent irradiance of the light field. The influence of the positioning error of the SAC on the light intensity distribution at the near-end of SAC is not apparent. WebJul 1, 2007 · As it was mentioned, we are interested in the synthesis of optical fields generated by means of an incoherent ensemble of DFF. This is obtained associating random features to the modulating function H(u, v) as it is shown below. The new optical field is generated by means of the irradiance superposition of these random diffracted free beams.
