When laser light illuminates a diffuse object, it produces a random interference effect known
as a speckle pattern. If there is movement in the object, the speckles fluctuate in intensity …

Laser Doppler velocimetry uses the frequency shift produced by the Doppler effect to
measure velocity. It can be used to monitor blood flow or other tissue movement in the body …

This textbook deals with fourier analysis applications in optics, and in particular with its
applications to diffraction, imaging, optical data processing, holography and optical …

Speckle Phenomena in Optics provides a comprehensive discussion of the statistical
properties of speckle, as well as detailed coverage of its role in applications. Some of the …

Since speckle plays an important role in many physical phenomena, it is essential to fully
understand its statistical properties. Starting from the basic idea of a random walk in the …

There have been three basic approaches to optical tomography since the early 1980s:
diffraction tomography, diffuse optical tomography and optical coherence tomography …

A method for dynamic, high-resolution cerebral blood flow (CBF) imaging is presented in this
article. By illuminating the cortex with laser light and imaging the resulting speckle pattern …

A photograph of a flow field is taken under laser illumination. If the exposure is short enough,
the velocity distribution in the field will be mapped on the photograph as variations in …

A new noninvasive technique for monitoring capillary blood flow has been developed.
Based on the phenomenon of time-varying laser speckle, it is a digital version of single …

The world around us appears as diverse and beautiful as it does owing to the fact that light is
scattered. Scattering plays two roles in the intricate process of image formation. First, it is the …
