Bendable Fiber Lens for Minimally Invasive Endoscopy
Laser &Photonics Reviews, EarlyView.Translating ex vivo imaging to minimally invasive in vivo applications is of outstanding scientific and socioeconomic relevance. 3D imaging based on tiny lensless fiber endoscopes requires complex setups and computational schemes, so far. Bridging this gap, imaging through a unique optical fiber that mimics the functionality of a lens but is minimally ...

Wavelength-multiplexed orbital angular momentum meta-holography
PhotoniXThe field of high-bandwidth holography has been extensively studied over the past decade. Orbital angular momentum (OAM) holography, which utilizes vortex beams with theoretically unbounded OAM modes as information carriers, showcases the large ...

Direct Inversion of Digital 3D Fraunhofer Holography Maps
, 2015 The Differential Fourier Holography (DFH) gives an exact mathematical solution of the inverse problem of diffraction in the Fraunhofer regime. After the first publication [1] the Differential Fourier Holography was successfully applied in many ...

Annales Henri Poincaré, 2000 A rigorous (and simple) proof is given that there is a one-to-one correspondence between causal anti-deSitter covariant quantum field theories on anti-deSitter space and causal conformally covariant quantum field theories on its conformal boundary. The correspondence is given by the explicit identification of observables localized in wedge regions in ...

High‐Speed Multimode Fiber Imaging Using Binary‐Modulated Silicon Photonics Optical Phased Array
Laser &Photonics Reviews, EarlyView.A multimode fiber imaging system at 500 frames per second is experimentally demonstrated. It is enabled by a p‐i‐n diode‐based silicon photonics optical phased array. To simplify the electrical driving of p‐i‐n diodes, a binary modulation method with a costumed‐designed digital driver circuit is proposed. Reconstruction of each frame takes only 0.1 ms,

Dynamic Multi‐Focus 3D Laser Nanoprinting Based on Two‐Step Absorption and Computational Holography
Laser &Photonics Reviews, EarlyView.Low single‐focus laser powers in two‐step‐absorption 3D laser nanoprinting make parallelization efforts a viable route to increase print speeds while still relying on compact continuous‐wave lasers. Herein, an established two‐step‐absorption photoresist system with computational holography based on a digital micromirror device is combined in order to ...
