Method for alignment error precision measurement of self-adaptive optical wave-front sensor and wave-front corrector

The invention discloses a method for alignment error precision measurement of self-adaptive optical wave-front sensor and wave-front corrector. By application of a voltage to a feature driver of the wave-front corrector, aberration change conditions in a light path are measured by a wave-front sensor, the position of the feature driver, in the light path, of the wave-front corrector can be obtained according to the measured aberration changes, and accordingly alignment errors of the driver of the wave-front corrector and the wave-front sensor can be obtained. By adoption of existing conditions in a self-adaptive optical system, addition of any extra devices is avoided, simplicity in implementation is realized, the alignment errors of the wave-front corrector and the wave-front sensor can be measured effectively, adjustment of the optical system is guided, and correction performance of the self-adaptive optical system is improved.
