New FPGA-based image-oriented acquisition and real-time processing applied to plasma facing component thermal monitoring

The surface temperature depends on the optical properties of the observed object and the transfer function of the optical system. This is not currently taken into account in the real-time processing. There a need for a powerful hardware with local memory. New industrial FPGA (Field Programmable Gate Array) is well adapted to real-time and complex processing for imaging diagnostics and FPGA architecture appears to be a good choice for real-time acquisition, local and 'intelligent' processing, compression and data transfer. First results on the Tore-Supra 2008 campaign concerning temperature evolution, hot spot detection and electrical arc recognition are presented. The system is limited by the current IR camera throughput. This document is composed of the slides of the presentation
