Abstract

A laser scanning system for measurement of the attitude angles of a fixed projectile is described. The angular information extracted from the temporal signal is dependent on the spatially sensitive reflection of the outer surface. Results from a laboratory based laser scanning system, operating over a distance of about 1 m, demonstrate the concept. Azimuth and elevation of a cylindrical projectile are recovered from the temporal signature obtained by scanning a laser spot across a bar pattern painted on its surface. Measurement accuracy and reproducibility are a function of the scan spot size, the contrast of the painted bar pattern and the overall timing accuracy of the composite system. Differential angular accuracy of 1 mrad has been demonstrated using a planar target.
