| Abstract(in English) | Using light-waves in a radar or a wireless LAN of a diffused type, the light is scattered on materials and propagates to the receiver. In such optical measurement or communication systems, speckles which are caused by randam scattered laser lights are acknowledged as a problem. In this research, the distance from a scatter to an observer (R), the laser beam size and the number of lasers are changed to investigate the effects to the speckle patterns on the basis of the FFT. We also analyzed the dependence of the speckle pattern on the scattering material. This paper describes the experimental results. |
