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…
