Leveraging target dynamics for imaging in complex media
Yoav Ben Haim, Ilay Tomer, Omri Haim +2
Optical imaging in complex samples such as biological tissues is fundamentally challenging due to random light scattering that degrades resolution and contrast. When imaging realis…
Leveraging natural fluctuations for matrix-based aberration correction in photoacoustic imaging
Yevgeny Slobodkin, Ori Katz
Photoacoustic imaging is the leading technique for deep tissue optical imaging, allowing single-shot imaging at depths. However, its resolution may be limited by acoustic aberratio…
Beyond memory-effect matrix-based imaging in scattering media by acousto-optic gating
Elad Sunray, Gil Weinberg, Moriya Rosenfeld +1
Imaging inside scattering media at optical resolution is a longstanding challenge affecting multiple fields, from bio-medicine to astronomy. In recent years, several groundbreaking…
Coherent Perfect Absorption of Arbitrary Wavefronts at an Exceptional Point
Helmut Hörner, Lena Wild, Yevgeny Slobodkin +3
A Coherent Perfect Absorber (CPA) exploits the interferometric nature of light to deposit all of a light field's incident energy into an otherwise weakly absorbing sample. The down…
Ptychographic lensless coherent endomicroscopy through a flexible fiber bundle
Gil Weinberg, Munkyu Kang, Wonjun Choi +2
Conventional fiber-bundle-based endoscopes allow minimally invasive imaging through flexible multi-core fiber (MCF) bundles by placing a miniature lens at the distal tip and using…
Noninvasive megapixel fluorescence microscopy through scattering layers by a virtual reflection-matrix
Gil Weinberg, Elad Sunray, Ori Katz
Optical-resolution fluorescence imaging through and within complex samples presents a significant challenge due to random light scattering, with substantial implications across mul…
