(28) フラクタル性を有するランダムな光強度の生成と特性
第22回ファジィシステムシンポジウム講演論文集，pp.3-6，2006-9
It is known that random optical intensities with fractal properties (fractal speckles) can be generated by illuminating an ordinary plane diffuser with coherent light having an average intensity obeying a negative power law. So far, such an illumination condition was realized by the laser light cattering from a random fractal aperture, giving rise to extremely weak intensities. In this paper, we introduce a new approach to generating power-law intensities on the basis of a liquid crystal spatial light modulator. This method provides us with much brighter fractal speckles than those due to the preceding method. Some properties of fractal speckles are also discussed, particluarly, in relation with the intensity clustering and multifractality.
