作为现代遥感技术最重要的发展之一，光谱成像仪在**、地质、海洋、大气探测等各个领域都有着广泛的应用。然而传统的色散或者干涉光谱成像仪由于需要多次曝光来扫描数据立方体，并不适合于场景快速变换的情况。四维(4D)光纤视场合成光谱成像仪，一种将特制光纤束置于望远镜的像面并成线性排列输出到光谱仪的技术，使得光谱成像仪能够通过单次曝光便获取目标的数据立方体，从而具有观测高速目标和瞬变现象的能力。搭建了一套桌面实验系统，在可见光谱段获得4.2 nm的光谱分辨率，对彩色目标的成像效果良好。对光纤束排列误差进行了分析，并给出了校准方法。

As one of the most important development of remote sensing, spectral imager has been widely used in military, geognosy, ocean and atmosphere measurement. However, the classic spectral imager, neither dispersive spectral imager nor Fourier transform spectrometer, which has to take multiple exposures to scan spectral data cube, do not suit with the situation that the scene change too fast. Four-dimensional (4D) fiber reformatting spectral imager, in which a special optical fiber bundle sits in the image plane of the telescope and has linearly aligned at the entrance to the spectrograph, can capture three-dimensional (3D) spectral data cube in a single exposure. So it enable to measure fast moving target or fast changing scene. A breadboard system in the laboratory is described, the average spectral resolution of the system is 4.2 nm in visible range, and a good imaging result of color target is got. The fiber bundle errors are analyzed, and the calibrating method is given.
