Effect of optical aberrations on laser speckle

Not Accessible

Your library or personal account may give you access

Abstract

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 απ. The effects of the type and severity of the primary aberrations on the normalized power spectral density and intensity contrast are examined.
