Field-putting technique of wide-field hyperspectral imager

This paper presents the development of an airborne pushboorm hyperspectral imager having a cross-track field of view of 42 degree and a 2×2 m ground sample distance (GSD) from a nominal 2 km flight altitude. In order to provide a wider field of view and higher spatial resolution to meet requirement for a typical earth observation mission, the field putting technique was applied in the development for the difficulty of design and fabrication of large field of view lens and large area array charged coupled device (CCD). The hyperspectral imager is composed of two imaging spectrometer which each has a cross-track field of view of 22 degree. The alignment accuracy of field putting is finer than 5% of instantaneous field of view; it will be maintained by optomechanical configuration after putting finally.
