成像光谱仪把二维成像技术和光谱技术有机地结合在一起，是具有重大潜力的对地观测仪器。近年来，随焦平面探测器推帚成像技术的发展，先进国家研制成功了超光谱成像仪，成为成像光谱技术的又一生长点。本文结合工作经验，介绍以硅面阵电荷耦合器件（ＣＣＤ）为探测器的推帚式超光谱成像仪ＰＨＩ的关键技术及发展前景。 Imaging spectroscopy combines two-dimensional imaging and spectroscopy organically and is a potential earth observation instrument. In recent years, with the development of push-plane imaging technology of focal plane detectors, advanced countries have successfully developed the hyperspectral imager and become another growing point of the imaging spectroscopy technology. Based on the working experience, this paper introduces the key technology and development prospect of push broom hyperspectral imager PHI with silicon surface array charge-coupled device (CCD) as the detector.
