| 摘要 |
<p>The device (1) has an active optical element (4) i.e. flexible mirror, arranged between or within multi-spectral optical systems (3) i.e. reflective optical systems, according to cassegrain-schema developed multi-spectral optical systems. Control elements for the active optical element are provided such that an aberration correction of spectral channels is made by the active optical element according to a time division process. Beam splitters (5) or filters are utilized for dividing the spectral channels. A detector (6) detects the spectral channels. An independent claim is also included for a multi-spectral observation method.</p> |
