Fast frequency reconstruction using Deep Learning for event recognition in ring laser data
The reconstruction of a frequency with minimal delay from a sinusoidal signal is a common task in several fields; for example Ring Laser Gyroscopes, since their output signal is a beat frequency. While conventional methods require several seconds of data, we present a neural network approach capable of reconstructing frequencies of several hundred Hertz within approximately 10 milliseconds. This enables rapid trigger generation. The method outperforms standard Fourier-based techniques, improvin…

Optical imaging technique unlocks hidden glycemic history for diabetes and cancer research
A National Taiwan University (NTU) interdisciplinary research team, led by Prof. Chi-Kuang Sun and Prof. Tzung-Dau Wang, has unveiled a optical imaging technique that enables the reconstruction of an individual's historical blood glucose patterns—information that has long been beyond the reach of current medical technology.

Eyes above the trees: LiDAR technology improves forest assessment with laser beams
Forests have been benefiting humanity since long before the health benefits of forest bathing were discovered. They are major carbon sinks that provide a wide range of ecosystem services, including timber and non-timber forest products, recreation, and climate regulation.

Powerful and precise multi-color lasers now fit on a single chip
A few years ago, researchers in Michal Lipson's lab noticed something remarkable. They were working on a project to improve LiDAR, a technology that uses lightwaves to measure distance. The lab was designing high-power chips that could produce brighter beams of light.
