    Fusion tokamaks are complex devices requiring many diagnostics for real time control of the plasma and off-line physical analysis. In current tokamaks, imaging diagnostics have become increasingly used for these two purposes. Such systems produce a lot of data encouraging physicists to use shared tools and codes for data access and analysis. If general purpose software programs for data display and analysis are widely spread, a need exists in developing similar applications for quantitative imaging data analysis applied to plasma physic. In this paper, we introduce a new integrated software program, named wolff, dedicated to this task. The main contribution of this software is to gather under the same framework different functionalities for (1) data access and display, (2) signal, image, and video processing, and (3) quantitative analysis based on physical models. After an overview of existing solutions for data processing in the field of plasma data, we present the wolff architecture and its currently implemented features. The capabilities of the software are then demonstrated through three applications in the field of physical analysis (heat and particle flux calculations) and tokamak operation (safety operation)

    International audienceCet article décrit une méthode du canal de propagation. Les directions d'arrivée sont juxtaposées sur des photos panoramiques 3D. L'ensemble appelé radiophoto permet la corrélation entre la mesure du canal et l'environnement. Les phénomènes physiques tels que la réflexion ou la dffraction sont facilement identifiés
