WebFor incoherent addition of the multiple element detectors in a random speckle field, the ratio of the mean to the standard deviation will scale as the square root of the number of independently measured speckles. This improved signal-to-noise ratio makes absolute amplitude measurements feasible in heterodyne detection.

Even though each speckle pattern has a contrast of unity, an incoherent sum of N uncorrelated speckle patterns reduces the speckle contrast by a factor of N1/2. razer mamba right click not working
