A FURTHER INVESTIGATION ON THE MULTIPLIC-ATIVITY OF IMAGE-PLANE SPECKLE NOISE
象面斑纹噪声相乘性的进一步探讨

In this paper, the multiplicativity of the partially polarized image-plane speckle noise is considered. After deriving the n-th order moment of the intensity of the speckled image, the multiplicative model of speckle noise is justified. The mean squared error of the model for partially polarized case is discussed. Finally, the validity of the multiplicative model for the incoherent superposition of n independent linearly polarized speckled images formed with identical illumination is treated.
