Widefield lensless endoscopy with a multicore fiber
Viktor Tsvirkun, Siddharth Sivankutty, Géraud Bouwmans +3
We demonstrate pixelation-free real-time widefield endoscopic imaging through an aperiodic multicore fiber (MCF) without any distal opto-mechanical elements or proximal scanners. E…
Complementary Speckle Patterns : deterministic interchange of intrinsic vortices and maxima through Scattering Media
Jérôme Gateau, Hervé Rigneault, Marc Guillon
Intensity minima and maxima of speckle patterns obtained behind a diffuser are experimentally interchanged by applying a spiral phase delay of charge to the impinging coher…
Extended field-of-view in a lensless endoscope using an aperiodic multicore fiber
Siddharth Sivankutty, Viktor Tsvirkun, Géraud Bouwmans +4
We investigate lensless endoscopy using coherent beam combining and aperiodic multicore fibers (MCF). We show that diffracted orders, inherent to MCF with periodically arranged cor…
Single shot polarimetry imaging of multicore fiber
Siddharth Sivankutty, Esben Ravn Andresen, Géraud Bouwmans +3
We report an experimental test of single-shot polarimetry applied to the problem of real-time monitoring of the output polarization states in each core within a multicore fiber bun…
Widefield lensless endoscopy via speckle-correlations
Amir Porat, Esben Ravn Andresen, Hervé Rigneault +3
Flexible fiber-optic endoscopes provide a minimally-invasive solution for imaging at depths beyond the reach of conventional microscopes. Current endoscopes require focusing and/or…
