IR-photorecorder KIT-2F: modification and certification tests

Results from investigation of the characteristics of a high- speed IR-photorecorder based on the ionization-type IR- camera KIT-2F and CCD-camera are presented. The photorecorder operate in the spectral range 1-10 micrometers with the frame exposure length of 1-100microsecond(s) , IR radiation detection threshold of 10 -6 J/cm 2 and spatial resolution of > 10 4 elem./frame. The photorecorder may be used for recording the structure of thermal fields in fast processes: in gas dynamics, ballistics, motor and aircraft building, pulsed welding and thermal treatment of surfaces, in powerful pulsed electric facilities et al. and for control of the IR laser radiation spatial characteristics.
