Self-focusing mirror scaling system of interference type super spectrum imager for satellite

An interferometric hyper-spectral imager self focusing calibration system in satellite, the slit components and pre-telescope of which are connected with each other. The optical terminal exit of the slit components is provided with a split, the posterior of the split is provided with a reflection component, which bonds with the self focusing lens fixed in the telescope as a whole. The optical axis of the self focusing lens and that of the pre-telescope are perpendicular to each other. A tungsten lamp is positioned on the optical axis of the self focusing lens; a heat absorbing glass is arranged between the self focusing lens and the tungsten halogen lamp. The utility model solves the technological problems such as the complicated background techniques structure, the inconvenient assembly and the low reliability. The miniature and the lightening of the structure improve the reliability of the system during moving in space.
