ABSTRACT:
Broadly, the disclosure is directed to a range-measuring detonating system comprising an air-driven scanning mirror which cooperates with fixed mirrors to project the output of a laser toward a target, the laser being modulated at a given frequency by a local oscillator and modulator circuit. Adjacent the laser is a detecting means which feeds a receiver, the receiver output being in turn delivered to a detector which feeds a phase comparator to which is also applied the output of the local oscillator. The phase comparator output is coupled to an AND circuit to which is also applied the output of the detector. When the light energy returned by a target in the vicinity of the system achieves a given phase and amplitude, the phase comparator output is gated through the AND circuit to ignite a squib, booster and warhead.
