DISPOSITIF DE TRAITEMENT D'UNE IMPULSION OPTIQUE POUR MESURER LE CONTRASTE DE CELLE-CI, ET SYSTEME DE MESURE DU CONTRASTE UTILISANT LE DISPOSITIF |
摘要 |
<p>Device for processing an optical pulse to measure the temporal contrast of this pulse, and system for measuring the contrast using the device. This device comprises: a device (2) receiving the pulse and providing the peak and pedestal of the pulse; a device (4) to create a temporal shift between the peak and the pedestal; a device (6) to attenuate the peak such that its level is of the same order of magnitude as the level of the pedestal; and a device (8) to multiplex the peak and the pedestal. The contrast is then equal to the ratio of the peak level to the pedestal level, these levels being corrected by the attenuations applied to them in the processing device.</p> |
