Plasma diagnostics using digital holographic interferometry [PDF]
arXiv, 2008 The advances in Charge Coupled Devices in one hand and the high resolution measurements of holographic technique on the other hand, we have adopted the method of digital real-time holographic interferometry for the diagnostics of high density plasma. The measured values of plasma electron density agree with the measurements from other techniques.

Inducing vortices in a Bose-Einstein condensate using holographically produced light beams [PDF]
, 2011 In this paper we demonstrate a technique that can create out-of-equilibrium vortex configurations with almost arbitrary charge and geometry in a Bose-Einstein condensate. We coherently transfer orbital angular momentum from a holographically generated light beam to a Rubidium 87 condensate using a two-photon stimulated Raman process.

Deep sound-field denoiser: optically-measured sound-field denoising using deep neural network [PDF]
arXiv, 2023 This paper proposes a deep sound-field denoiser, a deep neural network (DNN) based denoising of optically measured sound-field images. Sound-field imaging using optical methods has gained considerable attention due to its ability to achieve high-spatial-resolution imaging of acoustic phenomena that conventional acoustic sensors cannot accomplish ...

Advances in Quantum Imaging with Machine Intelligence
Laser &Photonics Reviews, Volume 18, Issue 8, August 2024.Quantum imaging exemplifies the fascinating and counter‐intuitive nature of the quantum world, where non‐local correlations are exploited for the imaging of objects by remote and non‐interacting photons. The field has exploded of late, driven by advances in the fundamental understanding of these processes, but also by advances in technology.
