Abstract
A device including an optical laser radiation source that emits laser radiation having a radially symmetric intensity profile and a mounting structure that engages a weapon barrel. An optical receiver including photodetectors located equidistant from and surrounding a central target site is locatable remote from the weapon. The photodetectors are sensitive to the laser radiation and each photodetector generates an electrical signal proportional to an intensity of the laser radiation received from the laser radiation source. A signal processor processes the electrical signals from the photodetectors to generate an intensity gradient indicating comparative intensity of the laser radiation that is detected by the photodetectors. The intensity gradient presents a null point when the intensity detected by at least two compared photodetectors is equal. A communicative link exists between the optical laser radiation source and the optical receiver. Synchronous modulation-demodulation of the laser source and detectors assists in optical noise exclusion.
