PURPOSE:To follow up a moving target by means of the shooting index on a fixed reticle, by having coincidence between the optical axis of a long-distance measuring system and that of an aiming mirror system and controlling an optical deflecting element on the optical axis to ensure the unified deflection of both optical axes. CONSTITUTION:A distance is measured by matching the standard line of measurement of a laser long-distance measuring system 70 with a target. In this case, the standard line of measurement is coincident with the shooting standard line of an aiming mirror system 90 containing a fixed reticle 94 of the system 90. The shooting index of the reticle 94 also serves as the long-distance aiming index. Thus the standard lines of measurement of both systems is set in the same direction as the axial line of a gun barrel, and the gun barrel directs the target. The output of this measurement of distance is fed to a computer to obtain the future correction value. Based on this correction value, an optical deflecting element 98 is controlled, and an optical axis 100 is directed to the future correction position out of the target. Then the shooting index line is controlled to coincide with the target. Thus the gun barrel is directed to the future target position. In such a way, the target is pursued with the shooting index on the reticle 84 although the target is moving. |
