Abstract:

A cold-background multi-target compounding system provides infrared targets for a hardware-in-the-loop simulation system, in which large aperture reflective mirrors are employed. In this paper, we propose a combined belt-back structure and design the flexible connection to solve the support mechanism of large aperture mirrors for 100 K temperature variations. By Finite Element Method analysis, the root mean square of the optimized mirror was better than λ/40 under self-gravity and 100 K temperature variations. By Zernike polynomial fitting, the modulate transmission function of the multi-target compounding system was over 0.5 and the root mean square spot diameter was less than 0.05 mrad. Results demonstrate that the proposed support mechanism was effective, providing analytical data for a 1 m level mirror for large environment temperature variations.
