Intensity correlations in perturbed optical vortices: Diagnosis of the topological charge
Patnala Vanitha, Bhargavi Manupati, Salla Gangi Reddy +3
We propose and experimentally verify a novel scheme for diagnosing the order of a perturbed optical vortex using its 2-D spatial autocorrelation function. The order of a vortex was…
Diffracting and Non-diffracting random fields
Patnala Vanitha, Bhargavi M, Venkateswarlu Annapureddy +3
We have generated and propagated both diffracting and non-diffracting speckles using the scattering of perfect optical vortices. The diffracting speckles have been realized in the…
Physical Unclonable Functions using speckle patterns of perfect optical vortices
Patnala Vanitha, Bhargavi Manupati, Inbarasan Muniraj +3
Encryption techniques demonstrate a great deal of security when implemented in an optical system (such as holography) due to the inherent physical properties of light and the preci…
Correlations in scattered perfect optical vortices
Patnala Vanitha, Nijil Lal, Anju Rani +2
We have studied correlations in the speckle patterns generated by the scattering of perfect optical vortex (POV) beams and used them for producing a new-class of coherence function…
A polarization gadget with two quarter wave plates: Application to Mueller Polarimetry
Salla Gangi Reddy, Shashi Prabhakar, Chithrabhanu Perumangattu +2
We show that there are number of ways to transform an arbitrary polarization state to another with just two quarter wave plates (QWP). We have verified this geometrically using the…
