Structure orientation determined in transmission and reflection: q-plate
Hsin-Hui Huang, Meguya Ryu, Shuji Kamegaki +9
Determination of orientation in the imaged sample/scene has a large application potential when the anisotropy of properties is analysed, usually, under a linearly polarised illumin…
Axial resolution post-processing engineering in Fresnel incoherent correlation holography
Shivasubramanian Gopinath, Joseph Rosen, Vijayakumar Anand
Fresnel incoherent correlation holography (FINCH) is a self-interference-based incoherent digital holography method. In FINCH, light from an object point is split into two beams, m…
Imaging with Diffractive Axicons Rapidly Milled on Sapphire by Femtosecond Laser Ablation
Daniel Smith, Soon Hock Ng, Molong Han +4
Fabrication of large area (sub 1 cm cross-section) micro-optical components in a short period of time (approximately 10 min) and with lesser number of processing steps is highly de…
All femtosecond optical pump and X-ray probe: holey-axicon for free electron laser
V. Anand, J. Maksimovic, T. Katkus +21
We put forward a co-axial pump(optical)-probe(X-rays) experimental concept and show performance of the optical component. A Bessel beam generator with a central 100 micrometers-dia…
Compact Three-Dimensional Quantitative Phase Contrast Imager
Vijayakumar Anand, Tomas Katkus, Denver Linklater +2
Detection of phase variations across optically transparent samples is often a difficult task. We propose and demonstrate a compact, lightweight and low cost quantitative phase cont…
A compact single channel interferometer to study vortex beam propagation
Sruthy J. Lathika, A. Vijayakumar, Shanti Bhattacharya
We propose and demonstrate a single channel interferometer that can be used to study how vortex beams propagate. The interferometer consists of a multifunctional diffractive optica…
