The imaging system installed on the RFX reversed field pinch experiment (R = 2 m, a = 0.45 m) with the principal aim of monitoring the plasma-wall interactions is described. The system includes various types of cameras. Standard rate (25 frames/sec) high resolution (768 × 576 pixels) CCD cameras have been used with tangential views in order to monitor an as wide as possible portion of the first wall surface. Faster cameras (up to 850 frames/sec) with low resolution or reduced field of view (fixed, 128 × 128, or variable pixel configurations) are employed to study detailed time evolution. A simple, PC based, image acquisition system allows quantitative analysis, with automatic recording and display. Several studies performed with the system by interposing proper interference filters, ranging from UV to near infrared, and by absolutely calibrating the cameras are briefly described.
