High speed, complex wavefront shaping using the digital micro-mirror device

Digital micro-mirror devices (DMDs) have been deployed in many optical applications. As compared to spatial light modulators (SLMs), they are characterized by their much faster refresh rates (full-frame refresh rates up to 32 kHz for binary patterns) compa ...

Performance Evaluation of Objective Image Quality Metrics on Conventional and Learning-Based Compression Artifacts

Touradj Ebrahimi, Evgeniy Upenik, Michela Testolina

Lossy image compression is a popular, simple and effective solution to reduce the amount of data representing digital pictures. In most lossy compression methods, the reduced volume of data in bits is achieved at the expense of introducing visual artifacts ...

On the 2D Post-Processing of Brillouin Optical Time-Domain Analysis

Luc Thévenaz, Zhisheng Yang, Simon Adrien Zaslawski

The benefits and limitations inherent to the 2D post-processing of measurements from Brillouin optical time-domain analyzers are investigated from a fundamental point of view. In a preliminary step, the impact of curve fitting on the precision of the estim ...

Experimental investigations on the load-carrying capacity of digitally produced wood-wood connections

Yves Weinand, Julien Gamerro, Jean-François Bocquet

The rise of digital fabrication has increased the use of wood-wood connections inspired by traditional carpentry in modern timber constructions. With recent developments on standard construction systems, the mechanical behavior of such joints for in-plane ...

Charge Neutralization and Direct Thrust Measurements from Bipolar Pairs of Ionic- Electrospray Thrusters

Herbert Shea, Daniel George Courtney

lectrospray (ES) thrusters are unique in their ability to emit both positive and negative beams, each contributing similarly to thrust. Spacecraft charging could be prevented without a dedicated neutralizer if currents of simultaneously emitted opposing po ...

Permanence and Persistence Conception, Construction and Conversion of Modern Cinema Theatres [1910-1939]

Joana de Almeida Gouveia Oliveira Alves

This work is based on the assumption that it is possible to achieve sustainable development by preserving the twentieth century heritage. Modern European cinemas were especially vulnerable to the passing of time: in a few decades buildings with tremendous ...

Toward direct light-to-digital conversion using a pulse-driven hybrid MOS-PN photodetector

Maher Kayal, Adil Koukab, Denis Sallin

In this Letter, a direct light-to-digital converter based on an MOS-PN photodetector driven by pulsed voltage is presented. The objective is to avoid any analog-to-digital or time-to-digital conversion and, thereby, to pave the way for a new generation of ...

On-Chip Digital Background Calibration of Pipelined Analog-to-Digital Converters using Digital Assistance to support Nonlinear Residue Amplification

Thomas Liechti

This thesis describes a novel digital background calibration scheme for pipelined ADCs with nonlinear interstage gain. Errors caused by the nonlinear gains are corrected in real-time by adaptively post-processing the digital stage outputs. The goal of this ...
