Abstract
An active optical fuze for detonating a missile warhead at a prescribed re is disclosed in combination with an optical guidance system target sensing head for a missile which incorporates an assembly of optical elements for receiving radiant energy from a target and wherein the optical axis of the receiving assembly is automatically rotated by guidance controlled means in response to received guidance radiation so as to track the target. A lasing diode is utilized as the fuze radiation transmitting device, the lasing diode being coupled to the receiving optical assembly and disposed coaxially therewith for emitting radiation outwardly along the optical axis of the receiving assembly such that the fuze radiation is automatically emitted in the target direction when the receiving assembly is rotated to track the target. The receiving assembly optics is utilized not only to receive the guidance radiation from the target, but also to receive the fuze transmitter radiations scattered by the target, these two signals being recovered by a signal processing means within the optical receiving assembly.
