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…
Common-path generation of stable cylindrical perfect vector vortex beams with arbitrary order
Arabinda Mandal, Satyajit Maji, Maruthi M. Brundavanam
A Highly flexible and efficient method of generating stable radially and Azimuthally polarized perfect optical vortex beams and all higher-order cylindrical vector vortex beams are…
Geometric phase associated with Poincaré beams due to unfolding of fractional optical vortex beams
Satyajit Maji, Aswini K. Pattanayak, Maruthi M. Brundavanam
Optical vortex beam of fractional order is generated by the diffraction of a Gaussian beam using computer generated hologram embedded with mixed screw-edge dislocation. Unfolding o…
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…
Effect of average number of reference speckles on the SNR of object retrieved using off-axis holographic technique
Abhijit Roy, Maruthi M. Brundavanam
The propagation of coherent light through a random scattering medium generates speckle pattern. Although the speckle is random in nature, the object information is scrambled into i…
