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.

Wavefront Reconstruction for a Holographic Modal Wavefront Sensor Based on Extreme Learning Machine
IEEE Photonics JournalThe intermodal crosstalk effect as well as the limited dynamic range of holographic modal wavefront sensors (HMWFSs) significantly affect their wavefront-sensing accuracy.

Depth‐enhanced light field camera system based on focus‐tunable geometric phase lens module
Journal of the Society for Information Display, EarlyView.We propose a GPL‐based LF camera that significantly extends the depth range over passive optics. During elemental image acquisition and LF rendering, chromatic aberration is compensated by adjusting reconstruction depth and magnification per color channel, with optimized GPL operations considering color‐dependent depth of focus.

Adaptive photoacoustic computed tomography
Photoacoustics, 2021 For many optical imaging modalities, image qualities are inevitably degraded by wavefront distortions caused by varying light speed. In optical microscopy and astronomy, adaptive optics (AO) has long been applied to compensate for such unwanted ...

Journal of the Society for Information Display, EarlyView.By using cholesteric liquid crystals as circular polarization filters in quarter‐waveplate condition GPL (QW‐GPL) based SIDH, a stable circular polarization state is ensured, which reduces color distortion and polarization noise, thereby significantly enhancing the reconstructed image quality in full‐color QW‐GPL‐based SIDH.

Fast single pixel modal wavefront sensing using neural networks [PDF]
arXivDynamic wavefront aberrations negatively impact a wide range of optical applications including astronomy, optical free-space telecommunications and bio-imaging. Wavefront errors can be compensated by an adaptive optics system comprised of a deformable mirror and wavefront sensor connected by a control loop. For satellite optical communications (SatCom),
