FIELD: physics.
SUBSTANCE: pulsed radiation sources can be any fast natural or artificial processes accompanied by a light flash. The apparatus, along with an electrooptical camera, consisting of an objective, an electrooptical converter having slit-type image scanning and an image processing and recording system, has a so called calibration channel comprising a system for picking up single pulses and a Fabry-Perot interferometer for generating a train of equidistant optical pulses, lying along the optical axis of the pulsed laser. The image recording system is a solid-state matrix image receiver connected to a computer, having a program for correcting the scanning coefficient of the electrooptical camera, based on comparison thereof with duration of time intervals between pulses in the train.
EFFECT: invention enables to take high-precision measurements of time characteristics of pulsed optical radiation in the nano-picosecond range.
