High-sensitivity high-speed compressive spectrometer for Raman imaging
Benneth Sturm, Fernando Soldevila, Enrique Tajahuerce +3
Compressive Raman is a recent framework that allows for large data compression of microspectroscopy during its measurement. Because of its inherent multiplexing architecture, it ha…
Compressive Sampling Approach for Image Acquisition with Lensless Endoscope
Stéphanie Guérit, Siddharth Sivankutty, Camille Scotté +3
The lensless endoscope is a promising device designed to image tissues in vivo at the cellular scale. The traditional acquisition setup consists in raster scanning during which the…
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…
Nonlinear imaging through a golden spiral multicore fiber
Siddharth Sivankutty, Viktor Tsvirkun, Olivier Vanvincq +3
We report two-photon lensless imaging through a novel golden spiral multicore fiber. This unique layout optimizes the sidelobe levels, field of view, cross-talk, group delay and mo…
Pump-probe micro-spectroscopy by means of an ultra-fast acousto-optics delay line
Xavier Audier, Naveen Balla, Herve Rigneault
We demonstrate femtosecond pump-probe transient absorption spectroscopy using a programmable dispersive filter as an ultra-fast delay line. Combined with fast synchronous detection…
