3D scanning microscopy through scattering surfaces using the optical memory effect
Harish Sasikumar, Gerwin Osnabrugge, Kirsten Gerritsma +2
Wavefront shaping allows light to be focused through scattering objects. However, the wavefront correction found is only valid in a small region called the isoplanatic patch. Here…
Mirror Symmetry in three-dimensional Multiple-Scattering Media
Sudhir K. Saini, Evangelos Marakis, Kayleigh Start +3
We investigate the effect of a mirror-symmetry plane in multiple-scattering media under plane-wave illumination along the symmetry plane. Designed and fabricated samples' optical t…
Generative adversarial network for super-resolution imaging through a fiber
Wei Li, Ksenia Abrashitova, Gerwin Osnabrugge +1
A multimode fiber represents the ultimate limit in miniaturization of imaging endoscopes. Here we propose a fiber imaging approach employing compressive sensing with a data-driven…
Model-based wavefront shaping microscopy
Abhilash Thendiyammal, Gerwin Osnabrugge, Tom Knop +1
Wavefront shaping is increasingly being used in modern microscopy to obtain distortion-free, high-resolution images deep inside inhomogeneous media. Wavefront shaping methods typic…
Blind focusing through strongly scattering media using wavefront shaping with nonlinear feedback
Gerwin Osnabrugge, Lyubov V. Amitonova, Ivo M. Vellekoop
Scattering prevents light from being focused in turbid media. The effect of scattering can be negated through wavefront shaping techniques when a localized form of feedback is avai…
The generalized optical memory effect
Gerwin Osnabrugge, Roarke Horstmeyer, Ioannis N. Papadopoulos +2
The optical memory effect is a well-known type of wave correlation that is observed in coherent fields that scatter through thin and diffusive materials, like biological tissue. It…
A convergent Born series for solving the inhomogeneous Helmholtz equation in arbitrarily large media
Gerwin Osnabrugge, Saroch Leedumrongwatthanakun, Ivo M. Vellekoop
We present a fast method for numerically solving the inhomogeneous Helmholtz equation. Our iterative method is based on the Born series, which we modified to achieve convergence fo…
