Physics:Muzzle reference system

Mirror type laser reflector assembly of CN08's dynamic muzzle reference system.

The mirror for the muzzle reference system on this Royal Ordnance L11 is inside the metal housing on top of the thermal sleeve.

A muzzle reference system (MRS) is a device used on most modern tank guns and some artillery systems that measures the bending of the barrel due to heat, gravity and other issues. It normally consists of a laser device and detector mounted at the breach end of the gun, often co-located with other optics like the gunner's sight, and a mirror at the muzzle. By measuring the deflection of the barrel, corrections can be applied by the ballistic computer to correct for changes as the gun is fired.
