It is learned from elementary textbooks that the angular resolution of a perfect optical
telescope is limited by diffraction to an angle in radians of about A ID, the ratio of the …

Principles of Adaptive Optics describes the foundations, principles, and applications of
adaptive optics (AO) and its enabling technologies. This leading textbook addresses the …

Since the invention of the laser there has been a growing interest in the random speckle
pattern that is generated when light from this highly coherent source is scattered by a rough …

Publisher Summary This chapter discusses the effects of atmospheric turbulence in optical
astronomy, summarizes the present state of the theory, reviews the experimental checks that …

When the first edition of Optical Interferometry was published, interferometry was regarded
as a rather esoteric method of making measurements, largely confined to the laboratory …

The most frequently used experimental techniques for measuring the spatial coherence
properties of classical light fields in the space–frequency and space–time domains are …

Stellar speckle interferometry is a technique for obtaining diffraction-limited resolution of
stellar objects despite the presence of the turbulent atmosphere which limits the resolution of …

We demonstrate a modification to the traditional prism-based wavefront-folding
interferometer that allows the measurement of spatial and temporal coherence, free of …

We present modified scanning-type wavefront folding interferometers (WFIs), which allow
spatial coherence measurements of non-uniformly correlated fields, where the degree of …

within multiple serial images of contrast medium? owing through a blood vessel is com …
