摘要
针对高分辨率成像光谱仪的应用要求,对大孔径静态干涉成像光谱仪在不同光照条件下进行了计算分析,表明这种成像光谱仪在能量利用率方面有明显优势.研制仪器的机载飞行试验结果表明,虽然机载试验在2004年12月份进行,太阳高度角在全年中最小,但是图像的个别地方仍会饱和.机载飞行试验进一步验证了干涉成像光谱仪的高通量特性,同时也说明,仪器的地元分辨率指标还有提高的潜力.
According to the requirement of high resolution imaging spectrometer, a Large Aperture Interferential Imaging Spectrometer （LASIS） was designed. The energy calculation of different illuminance proved its distinct advantage in aspect of energy utilization. The aviation experiments were carried out in December which the sun angle is the lowest during one year. The flying results validate ,hat LASIS has the characteristic of high energy utilization,because some areas of the images are saturated. In the mean time, the flight results also show that the instrument has the ability of improving its resolution.
