Abstract:
Systems, devices, and methods for determining a time of flight (TOF) of a first bullet fired from a gun to pass a target plane (116) of a target (102,214,414,614); determining a location of an aimpoint on the target (214,414,614) in an imager field of view (FOV) (216) relative to a disturbed reticle (210) at a time the first bullet (114) is fired by the gun; determining a location of the first bullet (114) relative to the location of the aimpoint on the target at the TOF in the imager FOV (216); and determining an updated location of the disturbed reticle (222) based on a difference between the location of the first bullet (114) and the location of the aimpoint on the target (214,414,614) at the time the first bullet crosses the target plane and a difference between the location of the disturbed reticle and the location of the aimpoint on the target at the time the first bullet was fired.
Abstract:
Systems, devices, and methods including a bullet (114,1102); a retroreflector array (1104) adhered to a base of the bullet (410, 610), the retroreflector array (1104) having prism facets with a periodicity between 0.2 mm - 2.0 mm; and a cover (1112) disposed over the retroreflector array and hermetically sealed at the base (1106) of the bullet (1102); where the cover (1112) is disposed over the retroreflector array (1104) in a first position prior to firing, and where the cover is released from the base of the bullet in a second position after firing.
