We report, what is to our knowledge, the first experimental realization of partially coherent bottle beams. It is shown that partially coherent bottle beams can be achieved by the focusing of partially coherent light with an axicon-lens system. The influence of the spatial coherence of the incident partially coherent light and other parameters, such as the radius of the limiting aperture of the...

We present a novel experimental technique that can differentiate unequivocally between chaotic light and coherent light with amplitude fluctuations, and thus permits us to characterize unambiguously the output of a laser. This technique consists of measuring the second-order intensity cross correlation at the outputs of an unbalanced Michelson interferometer. It is applied to a chaotic light so...

In this paper a comparison between two typologies of point-like scatterers in SAR images, named Persistent Scatterers (PSs) and Coherent Scatterers (CSs) is proposed. The PSs are detected through the analysis of large stack of data, implying their temporal stability, and have been principally used for SAR interferometric applications. Differently, CSs are detected in single SAR images through t...
