An anonymous reader writes: Military and police marksmen could see their rifle sights catch up with the 21st century with a fiber-optic laser-based sensor system that automatically corrects for even tiny barrel disruptions. Factors such as heat generated by previously fired shots, to a simple bump against the ground can affect the trueness a rifle barrel. The new system precisely measures the deflection of the barrel relative to the sight and then electronically makes the necessary corrections. With modern high-caliber rifles boasting ranges of up to two miles, even very small barrel disruptions can cause a shooter to miss by a wide margin.
