This contribution describes some aspects of calibration and experimental operation of a slow infra-red camera used at the COMPASS tokamak at IPP Prague. We focus on the camera limitations a ecting the experimental data (mainly temporal smoothing).
Data time deconvolution used to correct the eff ect of the long response time of the camera detector is described. Smaller part of the contribution is devoted to the design of a fast IR camera system planned for installation in COMPASS in 2014.
