- W2758167499 abstract "The effects of active correction for the telescopes' primary mirrors are often degraded because the axial fixed points of the primary mirrors usually aren't able to perform active correction. This paper analyzes this problem and proposes a modified active correction algorithm to eliminate the adverse influence of the axial fixed points. We use a 1.2m thin mirror to simulate the modified algorithm, it shows the modified algorithm can significantly eliminate the adverse influence of the fixed points and improve the mirror's active correction effect: the fitting error of the 1.2m thin mirror on the 5th Zernike aberration reduces from 13nm to 1.6nm, the fitting errors for other Zernike aberrations also significantly reduce." @default.
