The output speckle statistics are affected by deterministic aberrations present in an imaging system when the speckle is only partially developed. The speckle-power spectral density and intensity contrast are shown to depend on these aberrations. The rough target surface is modeled as a perfectly transmitting (reflecting) surface with uniform phase distribution over (−α, α), where α ≤ π. The effects of the type and severity of the primary aberrations on the normalized power spectral density and intensity contrast are examined.
