Taxonomy of hybridly polarized Stokes vortex beams
Gauri Arora, Ankit Butola, Ruchi Rajput +5
Structured beams carrying topological defects, namely phase and Stokes singularities, have gained extensive interest in numerous areas of optics. The non-separable spin and orbital…
Multi-modal on-chip nanoscopy and quantitative phase image reveals the morphology of liver sinusoidal enodthelial cells
David A. Coucheron, Ankit Butola, Karolina Szafranska +6
Visualization of three-dimensional morphological changes in the subcellular structures of a biological specimen is one of the greatest challenges in life science. Despite conspicuo…
Coherence-induced Polarization Effects in Vector Vortex Beams
Stuti Joshi, Saba N Khan, Manisha +2
We demonstrate theoretically and experimentally coherence-induced polarization changes in generic and higher-order vector vortex beams with polarization singularity. The prominent…
High space-bandwidth in quantitative phase imaging using partially spatially coherent optical coherence microscopy and deep neural network
Ankit Butola, Sheetal Raosaheb Kanade, Sunil Bhatt +7
Quantitative phase microscopy (QPM) is a label-free technique that enables to monitor morphological changes at subcellular level. The performance of the QPM system in terms of spat…
High spatially sensitive quantitative phase imaging assisted with deep neural network for classification of human spermatozoa under stressed condition
Ankit Butola, Daria Popova, Dilip K Prasad +8
Sperm cell motility and morphology observed under the bright field microscopy are the only criteria for selecting particular sperm cell during Intracytoplasmic Sperm Injection (ICS…
Optimal vector beams maintaining robust intensity profile on propagation through turbulence
Priyanka Lochab, Paramasivam Senthilkumaran, Kedar Khare
We report experiments on propagation of scalar and vector optical beams through random phase screens mimicking turbulence and show that the intensity profile of the beam containing…
Optical vortex array in spatially varying lattice
Amit Kapoor, Manish Kumar, P. Senthilkumaran +1
We present an experimental method based on a modified multiple beam interference approach to generate an optical vortex array arranged in a spatially varying lattice. This method i…
