Turbulence Impacted Wavefront Corrections Using Beam Modulation Technique
Shouvik Sadhukhan, C. S. Narayanamurthy
New experimental technique have been proposed to discuss the turbulence impact reduction using beam shaping technique. In first phase of experiments, turbulence Impacted Vortex bea…
Classical field statistical phase-space analysis of passive turbulence mitigation using PMMA dielectric media
Shouvik Sadhukhan, C. S. Narayanamurthy
This study examines the influence of optical turbulence on field statistics using a nonlinear reconstruction and quantum phase-space formalism. Turbulence-distorted intensity seque…
Spectral Switch Anomalies in Sagnac Interferometer with respect to Galilean Frame
Shouvik Sadhukhan, Saikat Sadhukhan, Maruthi M Brundavanam +1
We report the spectral switch shift around spectral anomalies in a gyroscopic Sagnac interferometer which is normally used to calibrate the angular momentum of a gyroscope. The spe…
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…
Controlled Modulation of Depolarization in Laser Speckle
Abhijit Roy, Rakesh K. Singh, Maruthi M. Brundavanam
A new technique based on superposition of two speckle patterns is proposed and demonstrated for controlled modulation of the spatial polarization distribution of the resultant spec…
Hybrid correlation holography with a single pixel detector
Rakesh Kumar Singh
The correlation holography reconstructs 3D objects as a distribution of two-point correlation of the random field detected by two dimensional detector arrays. Here, we describe a h…
