Contest between diverging k-vectors and astigmatism in an aberrated randomly scattered light
Abhijit Roy, Maruthi M. Brundavanam
The impact of astigmatism on randomly scattered light, here speckles which are generated from a ground glass (GG) plate, is investigated by studying the change in the shape of the…
Generalized theory of spatial coherence for superposition of two speckle patterns with polarization diversity
Abhijit Roy
A generalized theory of spatial coherence for superposition of two speckle patterns with polarization diversity is presented. The presented theory deals with superposition in diffe…
Spatial statistics of superposition of two uncorrelated speckle patterns with polarization diversity
Abhijit Roy
A detailed theoretical and experimental study on the effect of the superposition of uncorrelated speckle patterns with polarization diversity on the spatial statistics of the super…
Tracking the rotation of a birefringent crystal from speckle shift measurement
Kapil K. Gangwar, Abhijit Roy, Maruthi M. Brundavanam
The random intensity distribution observed due to the propagation of a coherent beam of light through a scattering medium is known as a speckle pattern. The interaction of the spec…
Polarization based intensity correlation of polarization speckle
Abhijit Roy, Maruthi M. Brundavanam
A new, different kind of intensity correlation, denoted as polarization based intensity correlation, is proposed and investigated to study the correlation between different polariz…
Non-invasive tracking of polarization rotation from speckle contrast measurement
Abhijit Roy, Rakesh Kumar Singh, Maruthi M. Brundavanam
A technique based on speckle contrast measurement is proposed and demonstrated to track the polarization rotation of an optical beam behind a scattering layer. It is shown that wit…
