Abstract: A multiple laser beam system comprises a laser device which is intended to be attached on or near the barrel of a rifle or the like such that triggering of the weapon activates the laser transmitter and results in the laser device producing a plurality of beams which by means of an adjustable diverging lens on the laser device may be defocused to produce an overlapping pattern. The beams are transmitted sequentially by the laser head assembly while timing of the transmission of the beams is controlled by electronic beam encoding logic. When the weapon is fired a mechanical-to-electrical transducer is energized and generates an electrical signal used to trigger the laser firing sequence. Visual indication means are provided to indicate that the laser timing sequence has been initiated. The light beam is detected by a target having a plurality of light sensing detectors. Whereby an indication of the accuracy of the aim of the weapon may be obtained.
