Abstract

Non common path aberrations (NCPA) are one of the main limitations to achieve ultimate performance of an adaptive optic system. These static optical aberrations are unseen by the wave front sensor and therefore not corrected by closed AO loop. We present experimental results of a new procedure of measurement and pre-compensation of the AO non-common path aberrations. This new procedure has been studied with simulations, and tested on the AO bench (BOA) at ONERA. Strehl Ratio (SR) obtained on the imaging path reaches 93 % @ 632.8 nm even for low SNR.
