Abstract

A two axis optical FLIR gimbal assembly for azimuth and elevation supporting an assembly of optical elements including five folding mirrors, one of which is a Mangin mirror, and six lenses which implement a wide stabilized field of regard and provide a magnification of the incident image. The gimbal assembly, moreover, includes a yoke structure which is driven about an azimuth axis and supports a stable body member which is independently driven about an elevation axis. An independently driven turret is also rotatable about the azimuth axis and shields the gimbal assembly from external forces such as an air stream passing over the fuselage of an aircraft.
