    摘要: A laser sensor system including a common optical bench that is configured to receive and process different beams of a high energy laser (HEL). The common optical bench is configured to handle the different beams using a modular set of optical components. Optical components of the common optical bench include a filtering device configured to reduce the power of the beams, a common collecting optical element that is configured to set an imaging position and focal length for the beams, a position sensitive detector (PSD) arrangement that is configured to measure angular and positional errors in the beams, and various compaction optical elements, such as mirrors, that are configured to enable compaction of the laser sensor system by increasing the focal length of the beams.

    摘要: A telescope includes a primary mirror, a secondary mirror configured to move along a first axis, and a tertiary mirror configured to move along a second axis. The secondary and tertiary mirrors are configured to move along respective axes in a synchronized manner to focus a beam of electromagnetic radiation from the primary mirror. The telescope further may include an anamorphic deformable mirror configured to achieve wavefront control and correction of optical aberrations. The telescope further may include a first linear actuator configured to move the secondary mirror along the first axis and a second linear actuator configured to move the tertiary mirror along the second axis.

    摘要: A torque motor includes a large area rotor, a stator surrounding at least a portion of the rotor, and a small air gap separating the rotor from the stator to allow frictionless thermal coupling between the rotor and the stator. Heat from the rotor is transferred to the stator by conduction. The stator contacts an inner surface for a housing of the torque motor for conductively coupling to a cold environment air flow exterior to the torque motor housing. The air gap may have a dimension of about 0.002 to 0.003 inches. The stator may be conductively coupled to the torque motor housing by one of a thermal gap pad or high conductivity thermal gap filling compound. Heat conduction from the rotor to the stator preferably occurs without rotation of the rotor.
