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…
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…
