Patent ID: 7603163

Claim:
A method of operating a targeting system, comprising: providing an adjustable optical assembly including a targeting marker in a path of a penetrating beam of a radiation source, the targeting marker being at least partially opaque to a penetrating beam emitted by the radiation source, and the targeting marker indicating a targeting point on a target axis, the optical assembly further including a sensible targeting beam device that is capable of providing a sensible targeting beam coaxial and coincident with the target axis; providing a first alignment target indicating a first alignment point at a first location in the path of the penetrating beam, the first alignment target being at least partially opaque to the penetrating beam; providing the sensible targeting beam coaxial and coincident with the target axis; adjusting the optical assembly so the sensible targeting beam impinges the first alignment point at the first location, and so an image provided by the receiver indicates the targeting point coincides with the first alignment point at the first location; recording information corresponding to a position of the target axis as a first alignment position; providing a second alignment target indicating a second alignment point at a second location in the path of the penetrating beam, the second alignment target being at least partially opaque to the penetrating beam; adjusting the optical assembly so the sensible targeting beam impinges the second alignment point at the second location, and so an image provided by the receiver indicates the targeting point coincides with the second alignment point at the second location; and recording information corresponding to a position of the target axis as a second alignment position.
