Single-shot Kramers-Kronig complex orbital angular momentum spectrum retrieval

Camille Sophie Brès, Jianqi Hu, Yujie Chen

Orbital angular momentum (OAM) spectrum diagnosis is a fundamental building block for diverse OAM-based systems. Among others, the simple on-axis interferometric measurement can retrieve the amplitude and phase information of complex OAM spectra in a few s ...

An Inertial Uni-Axial Interferometer-Based Accelerometer for Harsh Environments

Mark Edward John Butcher, Gerard Aliana Cervera

For high-impact devices, subsequent vibrations have as much influence on the deterioration of the mechanical structure as the impact itself. To mitigate the consequences of both impacts and resulting vibrations, it is crucial to accurately understand the p ...

Measurement and comparison of graphene-based resonant accelerometers

Driss Belkass

An accelerometer is a device used to measure acceleration. Acceleration is the rate of change of an object’s velocity, measured in square meters per second [m/s2] or g force. This type of device is used to detect vibrations or the orientation of certain sy ...

Mean-field dynamics of infinite-dimensional particle systems: global shear versus random local forcing

Elisabeth Agoritsas

In infinite dimensions, many-body systems of pairwise interacting particles provide exact analytical benchmarks for the features of amorphous materials, such as the stress--strain curve of glasses under quasistatic shear. Here, instead of global shear, we ...

Modelling, Simulations and Characterization of NEMS accelerometers based on graphene

Daniel Moreno Garcia

Accelerometers are widely used in industrial applications and consumer electronics. We can find them in automotive crash detection or fitness trackers. The majority are based on piezoresistive or capacitive effect which are limited by their large size. Thi ...

Micropipette calibration by differential pressure measurements

Philippe Renaud, David Vincent Bonzon

The pipetting of small volumes, typically ranging between a few and one thousand microliters (mu l), is widely used in many laboratories and essentially relies on air displacement to aspirate and dispense the liquid contained in a small plastic tip. While ...

Gravity-Insensitive Flexure Pivot Oscillators

Simon Nessim Henein, Ilan Vardi, Etienne Frédéric Gabriel Thalmann, Lennart Rubbert, Mohammad Hussein Kahrobaiyan

Classical mechanical watch plain bearing pivots have frictional losses limiting the quality factor of the hairspring-balance wheel oscillator. Replacement by flexure pivots leads to a drastic reduction in friction and an order of magnitude increase in qual ...

Effect of damping models on the simulation of seismic axial forces in a reinforced concrete bridge pier

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Manuel Jordan

Post-reconnaissance findings after recent earthquakes have shown that the effect of the vertical acceleration component of the ground motion can be more damaging than typically considered thus far, particularly in near-field regions where the ratio of vert ...

Resolving 1 million sensing points in an optimized differential time-domain Brillouin sensor

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Alejandro Dominguez Lopez

A differential pulse-width pair (DPP) Brillouin distributed fiber sensor is implemented to achieve centimetric spatial resolution over distances of several kilometers. The presented scheme uses a scanning method in which the spectral separation between the ...
