Abstract

The relationship between the dynamic range and the clipping threshold of a double-clipped correlation of integrated laser speckle intensity signals is discussed. In particular, the maximum dynamic range of the clipped correlation is evaluated. For α = 1 (α being the number of the integrated speckles), the maximum dynamic range occurs for the clipping threshold of In 2〈I〉, and the clipping threshold approaches the mean intensity 〈I〉 as the number of integrated speckles increases. On the other hand, the maximum dynamic range does not change and has the same value of Δ = 1/4 (Δ being defined as the dynamic range of the clipping correlation normalized by that of the nonclipping correlation), even if the number of the integrated speckles varies.
