Optical generation of a spatially variant two-dimensional lattice structure by using a phase only spatial light modulator
Manish Kumar, Joby Joseph
We propose a simple and straightforward method to generate a spatially variant lattice structures by optical interference lithography method. Using this method, it is possible to i…
Embedding a nondiffracting defect site in helical lattice wave-field by optical phase engineering
Manish Kumar, Joby Joseph
We present a technique to optically induce a defect site in helical lattice wave-field where the combined wave-field continues to maintain its nondiffracting (ND) nature. This is d…
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…
Transmission Structured Illumination Microscopy using Tilt-mirror Assembly
Krishnendu Samanta, Azeem Ahmad, Jean-Claude Tinguely +2
We present experimental demonstration of tilt-mirror assisted transmission structured illumination microscopy (tSIM) that offers a large field of view super resolution imaging. An…
Digitally reconfigurable complex 2D Dual lattice structure by optical phase engineering
Manish Kumar, Joby Joseph
We present a method to combine two periodic lattice wave-fields to generate a complex dual lattice wave-field which could be employed for microfabrication of corresponding 2D dual…
Unsupervised organization of cervical cells using high resolution digital holographic microscopy
Jyoti Mangal, Rashi Monga, Sandeep R. Mathur +4
We report results on unsupervised organization of cervical cells using microscopy of Pap-smear samples in brightfield (3-channel colour) as well as high resolution quantitative pha…
Generating a hexagonal lattice wave-field with a gradient basis structure
Manish Kumar, Joby Joseph
We present a new, single step approach for generating a hexagonal lattice wave-field with a gradient local basis structure. We incorporate this by coherently superposing two (or mo…
