ABSTRACT:
An apparatus and method which enables a weapon (usually on a test firing range) only when the weapon is aimed at a predetermined zone around a target. A transmitter subsystem comprising a strobe light, power supply and alignment scope is disposed at or near the target and oriented so as to transmit strobe light pulses of preselected pulse frequency, pulse duration and spectral content at a receiving subsystem. The receiving subsystem disposed at or near the weapon optically focuses the received strobe pulses on a detector, which provides electrical signals in accordance with the received pulses. These electrical signals are processed by detector electronics so that an enable signal is provided to the weapon only when a pair of pulses is detected within a preseslected time interval. In this way, the present invention prevents unwanted firing of the weapon when it is not properly aimed at the predetermined zone.
