  • Systems, methods, and apparatus for optical bore sight error measurement and correction
    Patent number: 9804250
    Abstract: Systems, methods, and apparatus are disclosed for determining bore sight error. An apparatus may include an optical lens and a collimated light source configured to emit a beam of collimated light having a first wavelength, where the beam of collimated light passes through the optical lens and parallel to an optical axis of the optical lens. The apparatus may further include a position sensitive detector configured to receive the beam emitted by the collimated light source, and identify a first position of the beam relative to the position sensitive detector. The apparatus may also include a processing device configured to generate a bore sight error metric based, at least in part, on the first position identified by the position sensitive detector. The bore sight error metric characterizes a difference between an actual position of a target object and a perceived position viewed by the optical lens.
