The proposed utility model relates to the field of electronics and can be used for measurements and investigations of pulsed infrared, visible or ultraviolet radiation accompanying the fast processes.; The technical result of the proposed technical solution is to reduce the measurement error installed length sweep with a ± 10% to ± 2% due to conduct calibration scan duration immediately before the radiation of the registration of the control signal is synchronized in time with the detected radiation, and to ensure constancy (invariability) optical path during calibration and in the process of registration of radiation.; The technical result in chronological electron-optical recorder pulsed radiation containing block micrometric slit image transfer unit, image converter, image block gain focon unit image pickup disposed on the same optical axis, and a unit pulsed illumination, the operation control units ESM achieved by that the RAR introduced a calibration unit consisting of a laser diode and an optical lens disposed on another optical axis disposed at an angle α = (50 ° ± 5 °) to the plane of the image intensifier photocathode controlling a laser diode input connected to the output of pulsed illumination, controlled by a signal synchronized in time with the detected radiation. 2 ill.
