Scattering-robust Imaging of Azimuthal Features with Enhanced Resolution
Nilakshi Senapati, Abhinandan Bhattacharjee, Anand K Jha
Imaging through scattering media remains a long-standing challenge in numerous real-world applications, ranging from medical imaging to long-distance sensing. Recently, illuminatio…
Super-resolution imaging of azimuthal features with illumination carrying OAM
Nilakshi Senapati, Abhinandan Bhattacharjee, Kedar Khare +1
Super-resolution imaging refers to imaging techniques that surpass the Rayleigh resolution limit. One standard way to achieve super-resolution is by structuring the phase of the fi…
An experimental technique for measuring radial coherence
Radhika Prasad, Nilakshi Senapati, Suman Karan +4
Coherence refers to correlations between field vibrations at two separate points in degrees of freedom such as space, time, and polarisation. In the context of space, coherence the…
Structured position-momentum entangled two-photon fields
Radhika Prasad, Sanjana Wanare, Suman Karan +3
Structured optical fields have led to several ground-breaking techniques in classical imaging and microscopy. At the same time, in the quantum domain, position-momentum entangled p…
Propagation-induced entanglement revival
Abhinandan Bhattacharjee, Mritunjay K. Joshi, Suman Karan +2
The practical implementation of free-space quantum information tasks requires entanglement to be sustained over long distances and in the presence of turbulent and noisy environmen…
Measurement of two-photon position-momentum EPR correlations through single-photon intensity measurements
Abhinandan Bhattacharjee, Nilakantha Meher, Anand K. Jha
The measurement of the position-momentum EPR correlations of a two-photon state is important for many quantum information applications ranging from quantum key distribution to coin…
Experimental demonstration of structural robustness of spatially partially coherent fields in turbulence
Abhinandan Bhattacharjee, Anand K Jha
Structured fields that are spatially completely coherent have been extensively studied in the context of long-distance optical communication as the structure in the intensity profi…
Controlling propagation of spatial coherence for enhanced imaging through scattering media
Abhinandan Bhattacharjee, Shaurya Aarav, Harshawardhan Wanare +1
It is known that a spatially partially coherent light field produces better imaging contrast compared to a spatially coherent field and that the contrast increases as the spatial c…
Generation of Gaussian Schell-model fields as mixtures of their coherent modes
Abhinandan Bhattacharjee, Rishabh Sahu, Anand K. Jha
Gaussian Schell-model fields are examples of spatially partially coherent fields, which in recent years have found several unique applications. The existing techniques for generati…
Two-shot measurement of spatial coherence
Abhinandan Bhattacharjee, Shaurya Aarav, Anand K. Jha
We propose and demonstrate an interferometric scheme for measuring the two-dimensional two-point cross-spectral density function in a two-shot manner. Our scheme comprises a Michel…
Efficient generation of propagation-invariant spatially-stationary partially coherent fields
Shaurya Aarav, Abhinandan Bhattacharjee, Harshawardhan Wanare +1
We propose and demonstrate a novel method for generating propagation-invariant spatially-stationary fields in a controllable manner. Our method relies on producing incoherent mixtu…
