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…
