Laser &Photonics Reviews, EarlyView.This review explores deconvolution techniques in optical coherence tomography (OCT), addressing resolution degradation from point‐spread functions (PSF). It reviews foundational principles (e.g., Richardson‐Lucy deconvolution) to advanced AI‐driven methods, emphasizing clinical translation and interdisciplinary collaboration. Real‐world implementations

, 2015 The concepts and considerations that could leads to the development of a novel kind of classes of wavefront sensors inwhich the information is retrieved by the absence of photons rather than from their presence are shown. In quantumoptics the concept of ”sensing” an object without actually having photons interacting with it is already known ...

Are physiological oscillations physiological?
The Journal of Physiology, EarlyView., 2023 Abstract figure legend Mechanisms and functions of physiological oscillations. Abstract Despite widespread and striking examples of physiological oscillations, their functional role is often unclear. Even glycolysis, the paradigm example of oscillatory biochemistry, has seen questions about its oscillatory function.

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 ...

Investigation on the wavefront stability of wavefront sensors
, 2006 This dissertation mainly describes the wavefront stability of light source for the wavefront sensing systems. Several investigations on three different light sources, white light, laser diode and He-Ne laser have been carried out for two wavefront sensing systems, Hartmann and Shack-Hartmann systems.

Full‐Space Spin‐Controlled Four‐Channel Metalens With Equal Power Distribution and Broad Bandwidth
Laser &Photonics Reviews, EarlyView.In article xxxxx, Alex M. H. Wong and co‐authors propose a multifunctional full‐space metalens supporting power‐efficient, broadband operation for four spin‐controlled output channels. The metalens separates an incoming wave into four equi‐power, spin‐decoupled and function‐decoupled waves (two transmitted and two reflected).
