| Abstract: | A method was proposed to character the magnetic fluid display device(MFDD) by using laser speckle inspection technology(LSIT).The display mechanism of MFDD was expatiated and the movement of magnetic particles was analyzed and simplified as a geometry model.By using laser speckle correlation method, the particles accumulation was studied.Meanwhile,the shape changing of magnetic fluid film was investigated by using speckle patterns mean contrast method.Experiment results show that LSIT is an efficient method to character the optical properties of MFDD. |
