ABSTRACT:
An optical apparatus, particularly suited for use in a ballistic measurement device, including a laser generating a laser beam, an optical means for expanding the laser beam in a plane, and an optical element, positioned between the laser and the optical means, for dividing the laser beam into a plurality of beams of substantially identical intensity so that a substantially uniform brightness results over the entire angle of divergence of the laser beam.
According to another embodiment, the optical apparatus is used in a photoelectric apparatus for ballistic measurement, such as velocity of moving projectiles, further including means for deflecting the expanded laser beam to produce a second laser beam parallel to and spaced from the expanded laser beam by a predetermined distance, a photoelectric converter positioned so that the second laser beam impinges upon the converter, and an evaluation circuit responsive to an output of the converter to measure the time delay between interruptions of the first and second laser beams by a moving projectile.
