FIELD: study of fast-going processes. SUBSTANCE: photodetector converts examined light signal to electric one which is used to trigger generator of delayed pulses. In this case there are formed two pulses of voltage sequential in time which are fed to generators opening two electrooptical shutters fitted with photoattachments. Photoregistration of object at two sequential moments of time on which basis radius of formation and rate of expansion are calculated is carried out with the aid of splitter of luminous flux into two fluxes identical in section. EFFECT: improved efficiency and authenticity of method. 2 cl, 1 dwg
