<p>An apparatus for enabling a user to orient the aiming axis (12) of an aimable device (10) at a desired orientation with respect to a line of sight from the user to a target. The apparatus includes a viewer (30) with an eyeport (46) through which the user observes the target, thereby establishing the line of sight, a viewer axis (31) with a fixed orientation with respect to the line of sight when the user observes the target, the aiming axis (12) with an actual orientation relative to the viewer axis, and a mechanism for projecting onto the eyeport an image representative of the actual orientation of the aiming axis (12) relative to the viewer axis (31). The apparatus also includes a transmitter (20), adapted to be rigidly mounted on the aimable device (10), for transmitting to the viewer an indication of the actual orientation of the aiming axis (12) relative to the viewer axis (30).</p> |
