Abstract

This paper describes a new optical method, the high speed Moire topography of the shadow, to measure the yaw angle of a free-flight projectile, in which, the equipment can be simplified, for it needs only one camera, but the older ones need at least two. The formula of the calculation are deduced and the errors are analyzed. The final experimental results of a free-flight projectile by the new method mentioned above show that the yaw angle of a free-flight projectile can be measured accurately with the dynamic Moire topography of the surface of the projectile. This new method is available.
