Abstract: Inversion of emissivity measured by coherence imaging spectroscopy diagnostic (CIS) in HL-2A tokamak with Tikhonov algorithm is introduced. After correcting the problems such as visual string deviation caused by camera positioning in HL-2A tokamak,and then the inversion of emissivity and velocity in J-TEXT tokamak is carried out with Tikhonov algorithm.

Key words: Tikhonov, Canoncical inversion, HL-2A tokamak, J-TEXT tokamak
