Reconstructing complex field through opaque scattering layer with structured light illumination
Aditya Chandra Mandal, Manisha, Abhijeet Phatak +2
The wavefront is scrambled when coherent light propagates through a random scattering medium and which makes direct use of the conventional optical methods ineffective. In this pap…
Structured transmittance illumination coherence holography
Aditya Chandra Mandal, Tushar Sarkar, Zeev Zalevsky +1
The coherence holography offers an unconventional way to reconstruct the hologram where an incoherent light illumination is used for reconstruction purposes, and object encoded int…
Measuring obscured OAM spectrum using Stokes fluctuations
Tushar Sarkar, Reajmina Parvin, Maruthi M. Brundavanam +1
A novel technique to measure the orbital angular momentum (OAM) spectrum of the beam obscured by a complex random media is proposed and experimentally demonstrated. This is realize…
Phase-space interpretation of spatial stationarity for coherence holography
Rishabh Kumar Bhalavi, Rakesh Kumar Singh
We extend the wide-sense spatial stationarity concept of coherence holography in the regime of phase-space using the wigner distribution function. We focus mainly on the incoherent…
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…
Complex field measurement in a single pixel hybrid correlation holography
Ziyang Chen, Darshika Singh, Rakesh Kumar Singh +1
We propose a new scheme for recovery of complex valued object in a single-pixel hybrid correlation holography. Idea is to generate an intensity correlation hologram by correlation…
