Paper Abstract

An optoelectronic method is described which is used for the simultaneous measurement of the projectile velocity and contour with the aid of only one light barrier. A measuring laser produces a very thin lighting row perpendicular to the trajectory. The time-dependent luminous flux is recorded using a pin diode mounted in the transmitted light beam. The velocity is determined as a quotient from the length of the projectile and its residence time in the lighting row. The luminous flux is proportional to the projectile contour, so that the profile can be reconstructed. Data are recorded with a 10 MHz-transient data logger. A device based on the aforementioned principles has already been tested with success.
