An all-optical technique enables instantaneous single-shot demodulation of images at high frequency
Swapnesh Panigrahi, Julien Fade, Romain Agaisse +2
High-frequency demodulation of wide area optical signals in a snapshot manner is a technological challenge that, if solved, could open tremendous perspectives in 3D imaging, free-s…
Theoretical optimal modulation frequencies for scattering parameter estimation and ballistic photon filtering in diffusive media
Swapnesh Panigrahi, Julien Fade, Hema Ramachandran +1
The efficiency of using intensity modulated light for estimation of scattering properties of a turbid medium and for ballistic photon discrimination is theoretically quantified in…
Real-time quadrature lock-in discrimination imaging through scattering media
Sriram Sudarsanam, James Mathew, Swapnesh Panigrahi +3
Numerous everyday situations like navigation, medical imaging and rescue operations require viewing through optically inhomogeneous media. This is a challenging task as photons, in…
Adaptive polarimetric image representation for contrast optimization of a polarized beacon through fog
Swapnesh Panigrahi, Julien Fade, Mehdi Alouini
We present a contrast-maximizing optimal linear representation of polarimetric images obtained from a snapshot polarimetric camera for enhanced vision of a polarized light source i…
