Abstract: A method of boresighting includes providing a weapon including a bore having a centerline axis and a boresight telescope coupled into the bore. The boresight telescope has a beam splitter therein which directs image information received from an aiming reference to an eyepiece of the boresight telescope which is off-axis relative to the centerline axis. A boresight camera accessory (BCA) is removably coupled to the eyepiece. The BCA includes an objective and a photodetector array, wherein the objective focuses the image information from the eyepiece to the photodetector array which generates sensing signals. The sensing signals are automatically transmitted to at least one remote viewer, and a viewable image of the aiming reference is displayed from the sensing signals. The remote viewer individually boresights the weapon using the viewable image and a view of the aiming reference through the bore.

Abstract: A telescopic sight which can be used for either nighttime or daytime operation and is particularly adaptable for use on weapons ranging from rifles to anti-tank weapons.A first embodiment includes a single objective and two parallel light paths, one for day viewing and one for night viewing. The objective forms the beginning of the night path. Separating mirrors transmit light from the objective along the night path and reflects light from the objective to the day path. The night path includes an image intensifier assembly. A mirror at the end of the night path reflects the light from the image intensifier assembly to a beamsplitter/combiner on the day path. The beamsplitter/combiner transmits the light from the day path and reflects the light from the night path along the same path to an ocular assembly for viewing.A second embodiment of the telescopic sight is similar to the first embodiment but contains two objective lens assemblies for collecting light, one for the night path and one for the day path.
