Fourier holographic endoscopy for label-free imaging through a narrow and curved passage
Wonjun Choi, Munkyu Kang, Jin Hee Hong +3
Ultrathin lensless fibre endoscopes offer minimally invasive investigation, but they mostly operate as a rigid type due to the need for prior calibration of a fibre probe. Furtherm…
Guidestar-free image-guided wavefront-shaping
Tomer Yeminy, Ori Katz
Optical imaging through scattering media is a fundamental challenge in many applications. Recently, substantial breakthroughs such as imaging through biological tissues and looking…
Using fiber-bending generated speckles for improved working distance and background-rejection in lensless microendoscopy
Noam Shekel, Ori Katz
Lensless flexible fiber-bundle based endoscopes allow imaging at depths beyond the reach of conventional microscopes with a minimal footprint. These multicore fibers provide a simp…
100,000 frames-per-second compressive imaging with a conventional rolling-shutter camera by random point-spread-function engineering
Gil Weinberg, Ori Katz
We demonstrate an approach that allows taking videos at very high-speeds of over 100,000 frames per second (fps) by exploiting the fast sampling rate of the standard rolling-shutte…
