Abstract

Multitarget compounding system is a decisive subsystem of the infrared hardware-in-the-loop simulation system and the concentric structure with dimpled mirror is a potential multitarget compounding system. By inducting the off-axis aberration, the effect of off-axis aberration on broadening beamwidth was investigated for the practical multitarget compounding system. A critical abaxial distance was found when the axial spherical aberration was equal to the focal length of small mirrors. Outgoing beamwidth was increasing with abaxial distances when abaxial distance was over the critical distance. A laboratory multitarget compounding system was designed to demonstrate the effect.
