Claim:
1. Projectile flight parameter measurement apparatus for a weapon having a gun barrel defining a central longitudinal axis extending between a breech end and an opposite, muzzle end, said weapon being operative to launch a projectile through said gun barrel, said flight parameter measurement apparatus comprising: (a) a tubular housing configured to be attached to the weapon to receive a launched projectile as it leaves the muzzle end of the gun barrel, said tubular housing having a longitudinal axis aligned with the central longitudinal axis of the gun barrel; (b) at least one beam emitter disposed in the housing for illuminating the projectile as it passes through the housing; (c) at least one electronic imager disposed in the housing for viewing the projectiles that are illuminated by the emitter and for producing electronic signals representing images of the projectile; (d) an electronic computational logic device, coupled to said at least one electronic imager, for processing said signals to determine at least one flight parameter of the projectile that has passed through the housing, said projectile flight parameters being selected from the group consisting of: (1) projectile yaw; (2) projectile spin; (3) projectile muzzle velocity.
