Lensless wide-field 3D fiber endoscopy through scattering media using synthetic wavelength holography
Muralidhar Madabhushi Balaji, Parker Liu, Patrick Cornwall +3
Minimally invasive imaging with fiber optic endoscopes is crucial for in vivo visualization of tissue morphology, as it supports applications such as early detection of tumors. How…
Intensity-Correlation Synthetic Wavelength Imaging in Dynamic Scattering Media
Khaled Kassem, Areeba Fatima, Patrick Cornwall +3
Imaging through dynamic scattering media, such as biological tissue, presents a fundamental challenge due to light scattering and the formation of speckle patterns. These patterns…
Exploiting Phase Light Modulators for Low-SWaP Real-time Wavefront Correction at High-Resolution
John M. Bass, Jeffrey Y. Chen, Gregory M. Nero +8
Wavefront correction and beam tracking are critical in applications such as long-range imaging through turbulence and free-space optical communication. For instance, adaptive optic…
A Multisensory Approach to Probing Scattering Media
Muralidhar Madabhushi Balaji, Danyal Ahsanullah, Prasanna Rangarajan
Non-invasive detection of objects embedded inside an optically scattering medium is essential for numerous applications in engineering and sciences. However, in most applications l…
Synthetic Light-in-Flight
Patrick Cornwall, Manuel Ballester, Stefan Forschner +3
Light-in-flight (LiF) measurements enable the visualization of light paths through arbitrary, volumetric scenes, making light-matter interactions at ultrafast timescales visible. T…
Exploiting wavelength diversity for high resolution time-of-flight 3D imaging
Fengqiang Li, Florian Willomitzer, Prasanna Rangarajan +1
State-of-the-art time-of-flight (ToF) based 3D sensors suffer from poor lateral and depth resolutions. In this work, we introduce a novel sensor concept that provides ToF-based 3D…
Synthetic Wavelength Holography: An Extension of Gabor's Holographic Principle to Imaging with Scattered Wavefronts
Florian Willomitzer, Prasanna V. Rangarajan, Fengqiang Li +3
The presence of a scattering medium in the imaging path between an object and an observer is known to severely limit the visual acuity of the imaging system. We present an approach…
