Abstract
An improved target sighting device of the type particularly suited for use on moving vehicles, such as military aircraft, and in which a vertically-disposed C-shaped elevation gimbal is supported for rotary movement about an elevation axis at the center of the gimbal to enable a vertically extending mirror on the gimbal to be aimed toward a target along a line of sight at one side of the gimbal, for reflection of target information along such axis and through the open end of the gimbal to a fixed optical pickup assembly. Improvement resides in the support of the open end of the gimbal by a ring bearing encircled by an annular flex pivot assembly that limits the extent of rotary aim-influencing vibration that can be transmitted from the exterior of the device to the gimbal and mirror circumferentially through the ring bearing by friction.
