Advances in Nanostenciling: resistless nanopatterning enables new applications

This paper presents the state-of-the-art of nanostencil as a direct and local patterning method. Stencil lithography is a high-resolution shadow mask technique that allows structuring surfaces without using the harsh process steps typically associated with ...

Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory stating how to overcome the classical Rayleigh-resolution limit. It is based upon a new resolution criterion in phase of coherent imaging process and its spatial resolution is thought to be only SNR limited. Recently, the experimental o ...

Saliency-driven Black Point Compensation

Sabine Süsstrunk, Albrecht Johannes Lindner

We present a novel framework for automatically determining whether or not to apply black point compensation (BPC) in image reproduction. Visually salient objects have a larger influence on determining image quality than the number of dark pixels in an imag ...

3D Near-Infrared Imaging Based on a Single-Photon Avalanche Diode Array Sensor

Matthias Wolf, Edoardo Charbon, Juan Mata Pavia

An imager for optical tomography was designed based on a detector with 128x128 single-photon pixels that included a bank of 32 time-to-digital converters. Due to the high spatial resolution and the possibility of performing time resolved measurements, a ne ...

Multi-Channel Amplifier-Discriminator for Highly Time-Resolved Detection

Matthieu Despeisse, François Eric Powolny

A low-power multi-channel amplifier-discriminator was developed for application in highly time-resolved detection systems. The proposed circuit architecture, so-called Nino, is based on a time-over-threshold approach and shows a high potential for time-res ...

Optimization of long-range BOTDA sensors with high resolution using first-order bi-directional Raman amplification

Marcelo Alfonso Soto Hernandez

In this paper we perform an optimization of Brillouin optical time-domain analysis (BOTDA) sensors for achieving high resolution over long sensing ranges using distributed Raman amplification. By employing an optimized first-order bi-directional Raman ampl ...

Fast Imaging of Blob Motion in TORPEX Plasmas

Ambrogio Fasoli, Ivo Furno, Davoud Iraji

To complement electrostatic probe measurements of plasma turbulence and study plasma structures with high spatial resolution, a nonperturbative direct imaging system has been developed on TORPEX. This system includes a fast framing Photron-APX-RS camera an ...

Scalable Feature Extraction for Coarse-to-Fine JPEG2000 Image Classification

Pierre Vandergheynst, Christophe De Vleeschouwer, Benoît Macq

In this paper, we address the issues of analyzing and classifying JPEG 2000 code-streams. An original representation, called integral volume, is first proposed to compute local image features progressively from the compressed code-stream, on any spatial im ...
