  • Enhancing Phase Measurement by a Factor of Two in the Stokes Correlation 
    Yadav, Amit; Sarkar, Tushar; Suzuki, Takamasa; Singh, Rakesh Kumar (Multidisciplinary Digital Publishing Institute (MDPI), 2023-05-23)
    Phase loss is a typical problem in the optical domain, and optical detectors only measure the amplitude distribution of a signal without its phase. However, an optimal phase is desired in a variety of practical applications, ...
  • Stokes correlation to estimate topological charge from the speckle pattern 
    Sarkar, Tushar; Singh, Rakesh Kumar (Springer Science and Business Media Deutschland GmbH, 2022-12-15)
    The orbital angular momentum (OAM) of the vortex or helical beam, connected with the topological charge (TC) of the beam, has been used as an alternative degree of freedom to encode and decode the information in the optical ...
  • Structured transmittance illumination coherence holography 
    Mandal, Aditya Chandra; Sarkar, Tushar; Zalevsky, Zeev; Singh, Rakesh Kumar (Nature Research, 2022-12)
    The coherence holography offers an unconventional way to reconstruct the hologram where an incoherent light illumination is used for reconstruction purposes, and object encoded into the hologram is reconstructed as the ...
