Chinas a new diagnostic means;
plasma-imaging system has been developed on the HL-2A tokamak;
with a basic understanding of plasma discharge scenario of the entire torus;
checking the plasma position and the clearance between the plasma and the first wall during discharge. The plasma imaging system consists of (1) color video camera;
(2) observation window and turn mirror;
(3) viewing & collecting optics;
(4) video cable;
(5) Video capture card as well as PC. This paper mainly describes the experimental arrangement;
plasma imaging system and detailed part in the system;
along with the experimental results. Real-time monitoring of plasma discharge process;
particularly distinguishing limitor and divertor configuration;
the imaging system has become key diagnostic means and laid the foundation for further physical experiment on the HL-2A tokamak.;
