| Popis: | A holographic technique for correcting aberrations in a telescope objective is presented. An image hologram of the aberrations is used as a correction plate to cancel out all the aberrations of the objective. Experimental results demonstrate diffraction-limited performance of the corrected telescope, as well as practical fields of view and a useful bandwidth ( approximately 100 nm) for an objective with 10lambda aberrations. |
