… The optical system for this experiment is the fore-runner of the speckle interferometers that
use a simple reference wave combined with the speckle pattern (see Sect. 6.3). It was later …

With its nearly 40 years of existence, speckle interferometry (SI) has become a complete
technique, widely used in many branches of experimental mechanics. It is thus a challenging …

… Although the speckle phenomenon in itself is a consequence … Since the speckle size can
be controlled by the F number of … be known as electronic speckle pattern interferometry (ESPI). …

… Figure 1 shows a schematic of the speckle interferometer used in this work. … interferometer
(DSPI) is a variation on electronic speckle pattern interferometers which processes speckle …

… interferometry was established in the mid-1960s and is based on holographic wavefront
reconstruction. Speckle interferometry developed from this work; it relies on the speckle effect …

Publisher Summary This chapter discusses the nature of the speckle pattern and defines
some of its basic characteristics. The speckle effect in optics is the generation of a random …

Since 2007, close binary and multiple stars are observed by speckle interferometry at the 4.1
m Southern Astrophysical Research (SOAR) telescope. The HRCam instrument, observing …

… Speckle interferometry can be regarded as a method of finding the modulus of the degree
of coherence in the far field of an incoherent source and is essentially the same as a method …

… (SOAR) with the speckle camera. This … speckle interferometry monitoring. Many orbits were
already computed for the first time or improved using data obtained during previous speckle …

… The essential difference with respect to ordinary speckle interferometry is that we preprocess
the speckle photograph I, to obtain new functions S,. These new function S, enable us to …
