Paper Abstract

Modern missile seekers operate in dual millimeter wave/infrared (MMW/IR) mode in order to enhance target detection. The same dual modality is required for their testing. The dual band test system calls for a combining element that can bring both MMW and IR beams to the same seeker head. Optical Holographic technique was used to overcome the fabrication problems associated with manufacturing large size (IR/MMW) beam combiner that should be transparent to MMW while reflecting IR beam. We designed and produced a surface relief holographic optical element (HOE) that satisfied beam combiner requirements. Since the uniform metal coating of any meaningful thickness would reflect most of MMW radiation, we have found a way to partially metalize the HOE, so that it becomes transparent for TM polarized MMW while maintaining excellent reflectance of IR.
