Abstract
A pulsed laser beam aiming apparatus is configured such that substantially 00% of the energy from a pulsed laser beam from a Q-switched pulsed laser device is accurately aimed at a distant target/obstacle in space. The pulsed laser beam is reflected off of a multifaceted polygonal mirror spinning about its axis and perpendicularly affixed to a rotatable azimuthal table wherein the spinning mirror provides elevational orientation, and, in conjunction with the rotatable azimuthal table, azimuthal orientation. Control circuit and associated equipment cause the Q-switched pulsed laser device to be triggered on when a facet of the mirror is in the proper elevational and azimuthal orientation for the pulsed laser beam to hit the target/obstacle. Correct aiming of the pulsed laser beam at the target/obstacle is accomplished when the coordinates thereof are specific only as an elevational angle .+-.5 above and/or below the horizon and an azimuthal angle between 0.degree. and 360.degree..
