An experiment was performed to study the correlation between laser speckle patterns
obtained at different wavelengths at a fixed point at the image plane. Results agree with a …

It is shown how the contrast of a polychromatic speckle pattern can be calculated from the
spectral coherence of the scattered amplitude. For gaussian surfaces and relatively narrow …

An experimental investigation is made of the effect of surface roughness on the statistical
distribution of image speckle intensity. A speckle pattern is formed by spatially coherent light …

The theory of partially developed speckle patterns is reviewed. Exact solutions for the
speckle contrast as function of surface roughness are calculated for two different surface …

The statistical properties of speckle intensity variations produced by coherent light in the far-
field diffraction plane of an iluminated area of an object are studied experimentally as a …

Two speckle patterns produced from the same rough surface by two different illuminations
are correlated. The correlation depends on the surface roughness. The two illuminations …

The properties of a speckle pattern are determined by the light source, the rough surface,
and the optical system. The degree of correlation of the intensities of two slightly different …

The surface roughness properties (ie the rms surface roughness and the correlation length)
of strong diffuse objects are investigated by using the speckle patterns which obeys the non …

Publisher Summary This chapter discusses the statistics of speckle patterns. The statistical
properties of a speckle pattern depend, in general, on both the coherence of the incident …

The surface-roughness dependence of the intensity correlation function of the speckle
pattern, produced in the Fresnel region with fully developed speckle-pattern illumination …
