AI Technical Summary
Existing off-axis three-mirror system design methods lack analytical foundations, rely on numerical calculations, and are prone to blind optimization. They are also difficult to effectively correct asymmetric aberrations, affecting imaging quality and system compactness.
A design method based on vector aberration theory is adopted. By analytically expressing the relationship between aberration and structural parameters, and combining line-of-sight adjustment and optical simulation optimization, the tilt and eccentricity of the reflector are optimized, and the mathematical correlation of the aberration field center offset vector is established to achieve efficient and reliable system design.
It improves the efficiency and reliability of off-axis three-mirror system design, ensures imaging quality and achieves system compactness, avoids the blindness of traditional methods, and enhances the imaging performance of large field of view and large aperture.
