Tapered multi-core fiber for lensless endoscopes
Fatima El Moussawi, Matthias Hofer, Damien Labat +7
We present a novel fiber-optic component, a "tapered multi-core fiber (MCF)", designed for integration into ultra-miniaturized endoscopes for minimally invasive two-photon point-sc…
Miniature 120-beam coherent combiner with 3D printed optics for multicore fiber based endoscopy
Siddharth Sivankutty, Andrea Bertoncini, Victor Tsvirkun +6
We report high efficiency, miniaturized, ultra-fast coherent beam combining with 3D printed micro-optics directly on the tip of a multicore fiber bundle. The highly compact device…
Compressive lensless endoscopy with partial speckle scanning
Stéphanie Guérit, Siddharth Sivankutty, John Aldo Lee +2
The lensless endoscope (LE) is a promising device to acquire in vivo images at a cellular scale. The tiny size of the probe enables a deep exploration of the tissues. Lensless endo…
Line-scan Compressive Raman imaging with spatio-spectral encoding
Camille Scotté, Siddharth Sivankutty, Randy A. Bartels +1
We report a line-scanning imaging modality of Compressive Raman technology with a single-pixel detector. The spatial information along the illumination line is encoded onto one axi…
Compressive Raman imaging with spatial frequency modulated illumination
Camille Scotté, Siddharth Sivankutty, Patrick Stockton +2
We report a line scanning imaging modality of compressive Raman technology with spatial frequency modulated illumination using a single pixel detector. We demonstrate the imaging a…
Single-shot non-interferometric measurement of the phase transmission matrix in multicore fibers
Siddharth Sivankutty, Viktor Tsvirkun, Géraud Bouwmans +4
A simple technique for far-field single-shot non-interferometric determination of the phase transmission matrix of a multicore fiber with over 100 cores is presented. This phase re…
