    Fabrication of large aspheric mirror continues to be a challenge in the research field about advanced optical manufacture. Some advanced optics manufacturing research,which focused on large aspheric mirror manufactured by Stressed Mirror Polishing (SMP),is developed. SMP based on mechanics of elasticity is a novel aspheric fabrication technology that could transform aspheric optical fabrication technology into sphere optical fabrication technology,which greatly improve the fabrication efficiency. Take fabricating a paraboloid mirror of Φ314 mm diameter and F/7 for example to analyze the optical fabrication technology progress of paraboloid in stressed-state. Rationality and effectiveness of SMP were investigated. Establishing measurement system of sphere and paraboloid to analyze the experiment result and adopting interferometer to get surface shape of finished paraboloid,PV=3.317λ,rms=0.489λ. The results indicate that the method of the SMP can be used to produce the revolution axisymmetric paraboloid mirrors with high precision and efficiency.
