Self-calibrating targeting sight
View Patent ↗A targeting sight having viewing optics, a focal plane array and an alignment frame having an aperture that defines a target area that is mounted proximal the muzzle of a weapon. Electronic processing means is provided to define a crosshair in the viewing optics. The alignment frame is illuminated with a beam and the reflected portion of the beam is received by the focal plane array and is processed to position the crosshair with respect to the aperture.
1. A targeting sight comprising:
an alignment frame comprising an aperture defining a target area,
the alignment frame mounted proximal a muzzle of a barrel of a weapon whereby the alignment frame defines the target area with reference to the muzzle,
a sight housing comprising optical viewing means,
a LIDAR element comprising a detector having a responsivity to a predetermined range of the electromagnetic spectrum, the LIDAR element configured for imaging the target area with the predetermined range and displaying a 3-D image representative of the target area in the optical viewing means,
display means for displaying a reticle at a predetermined position in the optical viewing means,
alignment frame illumination means configured to illuminate the alignment frame with the predetermined range, and,
electronic processing means configured to position the reticle at the predetermined position based on an illumination reflection from the alignment frame received by the detector.
2. The targeting sight of claim 1 wherein the alignment frame comprises a ring member having a predetermined diameter.
3. The targeting sight of claim 1 wherein the alignment frame comprises an electromagnetically reflective surface.
4. The targeting sight of claim 1 wherein the alignment frame illumination means comprises a laser having a wavelength of about the 0.05 microns to about the 12 micron range of the electromagnetic spectrum.
5. The targeting sight of claim 1 further comprising a rail having the housing and alignment frame fixedly attached thereto.
6. The targeting sight of claim 1 wherein the predetermined position is further calculated based on one or more physical variables selected from the group consisting of humidity, temperature, altitude, barrel angle, barrel temperature, air density, range, latitude and longitude, ammunition load data, projectile velocity, ammunition caliber, target range and ballistic coefficient.
