Abstract

A ball joint gimbal imaging system includes on-gimbal optics that reimage a front optical aperture to a smaller back optical aperture that moves with the rotation of the inner ball. Relay optics are configured to relay the back optical aperture to an electro-optic component mounted on the platform, off-gimbal. Relay optics includes a first two-axis steering element (on or off-gimbal) that is positioned and sized to cover the range of motion of the beam from the back optical aperture across the range of gimbal motion. The first two-axis steering element is controlled to steer the optical beam passing through the back optical aperture into a second off-gimbal two-axis steering element that is controlled to tilt the optical beam to align light along the central axis of the electro-optic element with the central axis of the front optical aperture on the inner ball, which is coincident with the gimbal pointing axis.
