Paper Abstract

Wide field of view (FOV) can provide the high efficiency of remote sensing. In this paper, the optical fiber array is used to connect the telescope and the spectrometer, which makes the configuration of the imaging spectrometer flexible and compact with large FOV. In the proposed system, the optical fiber array is coupled with slit, and relay the image of the slit into the several spectrometers with short field or several parallel fields in a single spectrometer. The optical fiber array can avoid the problems of linear array of imaging fiber bundles without slit, such as manufacture difficulty of the single row fiber bundles, breakage of fiber and the difficulty of alignment the fiber with the pixels of detector. The optical design of the telescope based on TMA and the imaging spectrometer based on Fery prism are detailed in this paper. Moreover, the pushbroom scan experiment demonstrates the feasibility of the optical fiber array in the imaging spectrometer.
