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…
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…
