一、成像光谱技术的意义和发展背景传统的光学技术中有两个重要领域——成像技术和光谱技术。借助成像技术,可获得客体的影像信息,研究其空间结构;借助光谱技术,可得客体的光谱信息,研究其物理特性。最近几年来,光学和光信号探测技术取得了迅速发展。与此同时,开发了实时的快速数据处理装置。这些成就带来了一种时机,有可能将成像技术和光谱技术融合成成像光谱技术,即准实时地获得研究对象的影像和每个像元的光潜分布。
First, the significance and development of imaging spectroscopy Background Traditional optical technology has two important areas - imaging and spectroscopy. With the aid of imaging technology, the object’s image information can be obtained and the spatial structure of the object can be studied. With the help of spectral technology, the object’s spectral information can be obtained and its physical properties can be studied. In recent years, optical and optical signal detection technology has made rapid progress. In the meantime, real-time, fast data processing devices have been developed. These achievements have given rise to an opportunity to integrate imaging and spectroscopy into imaging spectroscopy, ie to obtain the images of the subjects and the photo-latent distribution of each pixel in real time.
