摘要： A scanning sensor system comprising a light sensor and a scanning telescope. The scanning telescope includes at least two primary telescope mirrors supported (preferably symmetrically) about a primary-mirror rotation axis. Each of the primary telescope mirrors is oriented to receive incident light along an incident ray path that is not parallel to the primary-mirror rotation axis. The scanning telescope includes at least one additional telescope mirror positioned to alternately receive a first reflected light beam from a first one of the primary telescope mirrors and thereafter a second reflected light beam from a second one of the primary telescope mirrors, and to direct the reflected light beam into the light sensor along an optical path. A primary mirror drive rotates that at least two primary mirrors about the primary mirror rotation axis at a primary mirror angular instantaneous rate rotation. A half-angle derotation mirror is positioned to reflect a light beam in the optical path, and a derotation mirror drive rotates the derotation mirror about a derotation-mirror axis parallel to the primary mirror rotation axis at a derotation angular rate of rotation that is one-half of the primary mirror angular instantaneous rate of rotation during the active scan period. The primary telescope mirrors are preferably mounted in a housing.
