成像光谱数据在空间域的显示， 对与用户的图像解译和信息提取有着至关重要的作用。 目前， 对于成像光谱数据空间域显示方法的研究主要集中在光谱域数据立方体， 针对干涉型成像光谱数据的研究很少。 干涉型成像光谱数据的空间域图像显示通常采用的方法是将干涉数据反演， 然后采用光谱域图像显示的方法进行显示。 干涉型成像光谱数据反演至光谱域计算复杂， 耗时长， 这对于干涉型光谱数据的空间域实时显示提出了巨大挑战。 文章提出了干涉型光谱成像数据的空间域图像实时显示方法， 该方法采用不同的光程差权重实现了干涉数据立方体的灰度显示和真彩色显示， 推荐了三组权重系数用于干涉数据立方体的显示。 将传统并与经过光谱反演的空间域显示方法进行比较， 结果表明， 在相同空间域显示效果下， 该显示方法可大大提高显示速度， 并且显示时间随数据立方体的尺寸增长速度缓慢可以满足系统的实时性需要。

The requirements of imaging interferometer visualization is imminent for the user of image interpretation and information extraction. However, the conventional researches on visualization only focus on the spectral image dataset in spectral domain. Hence, the quick show of interference spectral image dataset display is one of the nodes in interference image processing. The conventional visualization of interference dataset chooses classical spectral image dataset display method after Fourier transformation. In the present paper, the problem of quick view of interferometer imager in image domain is addressed and the algorithm is proposed which simplifies the matter. The Fourier transformation is an obstacle since its computation time is very large and the complexion would be even deteriorated with the size of dataset increasing. The algorithm proposed, named interference weighted envelopes, makes the dataset divorced from transformation. The authors choose three interference weighted envelopes respectively based on the Fourier transformation, features of interference data and human visual system. After comparing the proposed with the conventional methods, the results show the huge difference in display time.
