Asymmetric imaging: Reciprocity bounds and manifestations
Romil Audhkhasi, Anna Wirth-Singh, Rose Johnson +6
Recent demonstrations of unidirectional imaging using diffractive multilayers have brought a concept akin to optical isolation to imaging, yet the fundamental limits of such asymme…
High resolution Fluorescence lifetime IMaging Micro-Endoscopy (FLIMME) using a single multimode fiber
Victoria Fay, Ye Pu, Omer Tzang +6
Endoscopic optical imaging using a single multimode fiber (MMF) has emerged as a promising approach for highly compact, minimally invasive, and high-resolution imaging. Unlike conv…
Aberration correction in epi-fluorescence microscopy using unknown speckle illumination
Evolene Premillieu, Antonio M. Caravaca-Aguirre, Simon Labouesse +2
Diffraction-limited imaging in epi-fluorescence microscopy remains a challenge when sample aberrations are present or when the region of interest rests deep within an inhomogeneous…
Multiview Scattering Scanning Imaging Confocal Microscopy through a Multimode Fiber
Sakshi Singh, Simon Labouesse, Rafael Piestun
Confocal and multiphoton microscopy are effective techniques to obtain high-contrast images of 2-D sections within bulk tissue. However, scattering limits their application to dept…
Roadmap on Wavefront Shaping and deep imaging in complex media
Sylvain Gigan, Ori Katz, Hilton B. de Aguiar +42
The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow to understand and control light propaga…
Measuring the Transmission Matrix of a scattering medium using Epi-Fluorescence light
Evolene Premillieu, Rafael Piestun
There are several methods to focus light behind a scattering medium, but very few use fluorescence light as feedback or can be used without access to the distal side of the scatter…
Hybrid photoacoustic/fluorescence microendoscopy through a multimode fiber using speckle illumination
Antonio M. Caravaca-Aguirre, Sakshi Singh, Simon Labouesse +3
We present an ultra-thin hybrid imaging system based on an optical multimode fiber (MMF) and an optical fiber hydrophone that combines optical resolution photoacoustic and fluoresc…
Wavefront shaping in complex media at 350 KHz with a 1D-to-2D transform
Omer Tzang, Eyal Niv, Sakshi Singh +3
Controlling the propagation and interaction of light in complex media has sparked major interest in the last few years. Unfortunately, spatial light modulation devices suffer from…
Deep brain fluorescence imaging with minimally invasive ultra-thin optical fibers
Shay Ohayon, Antonio Miguel Caravaca-Aguirre, Rafael Piestun +1
A major open challenge in neuroscience is the ability to measure and perturb neural activity in vivo from well-defined neural sub-populations at cellular resolution anywhere in the…
Wave-front shaping in nonlinear multimode fibers
Omer Tzang, Antonio M. Caravaca-Aguirre, Kelvin Wagner +1
Recent remarkable progress in wave-front shaping has enabled control of light propagation inside linear media to focus and image through scattering objects. In particular, light pr…
Transmission-matrix-based point-spread-function engineering through a complex medium
Antoine Boniface, Mickael Mounaix, Baptiste Blochet +2
We report a method to design at will the spatial profile of transmitted coherent light after propagation through a scattering sample. We compute an operator based on the experiment…
Super-resolution photoacoustic imaging through a scattering wall
Donald B. Conkey, Antonio M. Caravaca-Aguirre, Jacob D. Dove +3
Imaging through opaque, highly scattering walls is a long sought after capability with potential applications in a variety of fields. The use of wavefront shaping to compensate for…
Sparse reconstructions of overlapping three-dimensional point spread functions using overcomplete dictionaries
Anthony Barsic, Ginni Grover, Rafael Piestun
When a single molecule is detected in a wide-field microscope, the image approximates the point spread function of the system. However, as the distribution of molecules becomes den…
Real-time resilient focusing through a bending multimode fiber
Antonio M. Caravaca-Aguirre, Eyal Niv, Donald B. Conkey +1
We introduce a system capable of focusing light through a multimode fiber in 37ms, one order of magnitude faster than demonstrated in previous reports. As a result, the focus spot…
