Paper Abstract

There are given the research data of photographic systems characteristics based on the ionization-type semi-conductive chambers (ITSC) with photodetectors of different types. The recorder dynamic range of 103,speed of response of 10-8s, resolution of 10 lines/mm and sensitivity of . 10-4-10-7 J/am2 In 1-10,6 )μm spectral range were obtai ned by optimizing the photodetector parameters,.the chamber design and its operating mode. Energy distribution in beams of pulsed HF and DF chemical lasers in the mode of "magnifying glass of time" was studied using ITSC. It is shown, that the energy distribu-tion on the lasers end has larger irregularity (,102 times) than at the integrated survey. The information has been received about space - time responses of CO2 lasers radiation with the aid of ITSC, operating in a modulation mode of emission at the chamber input,and on the chamber electrodes there is applied pulsed supply voltage with a photography frequency of 20-100 Hz. There are given the results of recording with ITSC of the heat fields structures of different objects over a temperature range 600-2000°C, which are heated by a shock wave or fly at the supersonic velocity at the frame exposure time of 10-10-5s.
