The power flow to the DIII‐D divertor targets is routinely measured using infrared (IR) thermography. An IR television camera sensitive to radiation in the 8–12‐&mgr;m range views the divertor region using a set of germanium optics. Digital signal processing is used to extract the desired surface temperature profiles from the analog data (&bartil;12 Mbytes) stored on videotape. Inversion of these data using a simple matrix formulation of the inverse heat conduction problem then yields the incident heat flux as a function of space and time. Results from a DIII‐D discharge are included.
