Abstract:
A stabilized optical gimbal assembly, comprising;turret means including a relatively large aperture rotatable about a first axis;a yoke located within the turret means and being independently rotatable about said first axis;a stable body member mounted on and supported by the yoke and being independently rotatable about a second axis orthogonal to said first axis;a first lens mounted across a forward portion of the stable body member and being oriented toward a predetermined line of sight;a first mirror having a central aperture mounted on the stable body member behind the front lens and angulated relative thereto;a second mirror mounted on said stable body member to one side thereof and adjacent said first mirror for receiving optical energy reflected therefrom and directing said optical energy through said central aperture;a second lens mounted on said stable body member behind said first mirror and aligned with said central aperture;a third mirror mounted on said yoke in alignment with said second lens and angulated relative thereto for receiving optical energy from said second lens and directing said energy through an opening in a rear portion of the stable body;a first lens assembly located in said opening for receiving optical energy from said third mirror;a fourth mirror angularly mounted on said yoke behind said stable body member for receiving optical energy from said first lens assembly;a fifth mirror angularly mounted on said yoke beneath said stable body member for receiving optical energy from said fourth mirror;and a second lens system mounted on said yoke for receiving optical energy from said fifth mirror and directing optical energy out of the gimbal assembly.
