Electrospinning for nano‐ to mesoscale photonic structures

Nanophotonics, Volume 6, Issue 5, Page 765-787, March 2017., 2017
Abstract The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small‐scale photonic devices are created by traditional microfabrication techniques that create features by processes such as lithography and electron or ion beam direct writing ...

Continuous-Time Fast Motion of Explosion Fragments Estimated by Bundle Adjustment and Spline Representation Using HFR Cameras

Applied Sciences, 2021
This paper introduces a continuous-time fast motion estimation framework using high frame-rate cameras. To recover the high-speed motions trajectory, we inherent the bundle adjustment using a different frame-rate strategy.

Detailed Analysis of the Timing Measurements in Optical Position Sensing Devices Based on Laser Beam Deflection

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016
I present a detailed analysis of the timing signals observed, when measuring the oscillation of a Lissajous scanner by sending a reflected laser beam onto carefully placed trigger diodes. This technique was used in a device which we have developed recently for the measurement of resonant MEMS scanner mirrors.

MOEMS-Based Scanning Light Barrier

Procedia Chemistry, 2009
AbstractThis work deals with the development of a novel MOEMS-based platform for miniaturised 1D or 2D light barrier systems. As outlined below, such a device could be used to project a classical linear light barrier, but could equally be used to produce curved perimeters and/or even full-volume light barriers.
