6. The nonlinearity in the response of the CCD detector is described by the power law (Formula presented), where (Formula presented) is the intensity of the light impinging onto the CCD. The linearization of this relation for small intensity fluctuations yields Eq. (2), where (Formula presented). The contrast (Formula presented) can be measured independently by using a sample with a well known intensity probability distribution (Formula presented). In our case the calibrating sample was a ground glass illuminated by the spatially filtered 632.8 nm line of a He-Ne laser beam, so that the CCD camera was illuminated by a speckle field with a Gaussian probability distribution.
