Embodiments of a laser imaging system with uniform line illumination and method for generating images are generally described herein. In some embodiments, the laser imaging system includes a polarizer beam splitter to angularly separate an input laser beam into a pair of overlapping cross-polarized beams having a first angular separation therebetween, and a diffraction optic beamlet generator to generate a plurality of beamlets of alternating polarization states with a second angular separation therebetween. The laser imaging system may also include a focal-plane array (FPA) having a field-of-view (FOV) to be illuminated by the plurality of beamlets.

There is disclosed a multimode seeker including an imaging infrared seeker and a radio frequency seeker. The imaging infrared seeker and the radio frequency seeker may share an optical system adapted to form an infrared image of an outside scene on a focal plane array image detector and to collimate radio frequency radiation transmitted from a radio frequency transceiver and focus millimeter ware radiation received from the outside scene onto the radio frequency transceiver. The shared optical system may include a plurality of baffles to block sunlight from reaching the focal plane array image detector, each baffle comprising a material that is opaque to infrared radiation and transparent to radio frequency radiation.

According to an embodiment of the disclosure, a system for providing thermal management of an obscured laser system is provided that includes a primary mirror, a secondary mirror, and a plurality of energy redirectors. The primary mirror is configured to reflect beam energy for the laser system. The secondary mirror is configured to function as a limiting aperture for the laser system and is aligned on-axis with respect to the primary mirror. The energy redirectors are each configured to redirect energy away from a corresponding obscuration and out of the laser system.

Methods and apparatus for guidance systems according to various aspects of the present invention operate in conjunction with a projectile including a guidance system having a guidance controller, a detector, and an optical system. The guidance controller controls the path of the projectile according to signals from the detector. The detector generates signals according to an angle of incident energy. The optical system transfers the energy to the detector via a spreader and a condenser. The spreader spreads the incident energy, and the condenser converges the spread energy onto the detector.

A beam director subsystem and method for use in a weapons system. The beam director subsystem includes a source of electromagnetic radiation for generating a high energy laser (HEL) beam. The electromagnetic radiation is directed to a secondary mirror that reflects the electromagnetic radiation to a primary mirror for output of the HEL beam. The secondary mirror is generally curved and expands the electromagnetic radiation received from the source prior to outputting the HEL beam from the primary mirror. The subsystem further includes a track telescope coupled to the housing. The track telescope has a track detector configured to receive electromagnetic radiation originating from the HEL and electromagnetic radiation emitted from an illuminator and reflected from an airborne target.
