METHOD FOR DEFINITION OF MOVING SURFACE ASYMMETRY

摘要

FIELD: physics, measurements. ^ SUBSTANCE: invention is related to the field of metering equipment, namely to measurement of moving surface parametres. Charge of explosive substance is initiated with the help of lens or detonation distributor on surface, which is speeded up by explosion products to velocity that causes glow of shock wave in front of it. Receiver of the same shape closed by screen is installed on motion route. Two or more groups of electro-optical detectors are installed in receiver along normal line to moving surface on different bases from initial position of surface. Surface of screen inverted to electro-optical detectors in process of motion interacts with their ends, besides, at the same time electric and light signals are generated, which are supplied to recorders. Recorders measure time of moving surface approach to the end of every detector. Diversity is defined by difference of times of electric and light signals in every group of detectors. ^ EFFECT: makes it possible to improve reliability and accuracy of measurements of time intervals in complex expensive experiments. ^ 4 dwg
