Abstract
Thermal deformations of gun/tank components can affect the firing accuracy of modern tanks. To alleviate this problem, an optical gun muzzle sensor has been designed to provide corrections to the computer-generated signals responsible for fire control. This paper first summarizes some typical deformations that induce firing inaccuracies, then reviews various optical approaches to sensing the angular position of a gun and finally, discusses the design of an optical instrument recently developed in Canada for this purpose. The technique involves a laser diode transmitter/receiver mounted on a turret roof and a small mirror at the gun muzzle to reflect the laser beam. Thermal distortions induce a beam deflection which is measured by an analogue, two-axis position sensing detector whose output signals are converted into angular corrections and sent to the fire control computer. The optical design and some specific engineering problem's are thoroughly discussed.
