Progress on the ITER H&CD EC Upper Launcher Steering-Mirror Control System

Timothy Goodman, René Chavan, Federico Alberto Alfredo Felici, Jean-Daniel Landis, Frédéric Dolizy, Francisco Sanchez, Robert Bertizzolo

The ITER Heating and Current Drive Upper Launcher (H&CD EC UL) uses a pneumomechanical steering-mirror assembly (SMA) to steer the RF beams for their deposition in the appropriate location in the plasma to control magnetohydrodynamic activity (neoclassical ...

Progress On The Iter Upper Launcher Millimeter Wave Design And Testing

René Chavan, Federico Alberto Alfredo Felici, Frédéric Dolizy

The main purpose of the ITER ECH upper launcher is to control magnetohydrodynamic activity, in particular neoclassical tearing modes, in the plasma. The mm-wave optical system is optimized to insure that the eight RF beams are all focused to a small beam w ...

The Marr Wavelet Pyramid and Multiscale Directional Image Analysis

Michaël Unser, Dimitri Nestor Alice Van De Ville, Daniel Sage, Katarina Balac

The “Marr wavelet pyramid” is a wavelet decomposition that implements a multiscale version of the complex gradient-Laplace operator. It is closely linked to a multiresolution analysis of

L _{ 2 }

(\mathbb{R} ^{ 2 }

) and it has a fast filterbank im ...

Miniature Cameras for Ultra-Light Flying Robots

Adam Klaptocz

The Laboratory of Intelligent Systems (LIS) at the Swiss Federal Technical Institute at Lausanne (EPFL) is working on a project to create an autonomous flying robot that uses ‘vision’ (i.e. optical flow) to maneuver through small spaces such as corridors i ...

Human walking along a curved path. I. Body trajectory, segment orientation and the effect of vision

Grégoire Courtine

Task‐related characteristics of gait and segment orientation during natural locomotion along a curved path have been described in order to gain insight into the neural organization of walking. The locomotor task implied continuous deviation from straight‐a ...

Liquid crystal on silicon beam deflector

Demetri Psaltis, Xiao Wang

A high efficiency, low cost, low voltage operation liquid crystal on silicon (LCOS) beam steering device with multiple angles addressing capability is developed. Currently, seven steering angles with as high as 92.7% efficiency are achieved within 2.85v. T ...
