The invention discloses a snapshot type infrared hyperspectral imaging system and method based on a slitting mirror, and the method comprises the steps: segmenting a target image into strips through the slitting mirror, and reflecting the strips to different positions of a detector according to a certain rule, so as to form different spectrum channels. A light splitting element is added in each channel, a blank area of the detector is filled with spectral information, and real-time detection of a three-dimensional data cube is achieved. Compared with a traditional infrared hyperspectral imaging system, the infrared hyperspectral imaging system has the advantages of real-time imaging, no moving part and high luminous flux, and can realize rapid identification, monitoring and early warning of a target. 本发明公开一种基于分切镜的快照式红外高光谱成像系统及方法，采用分切镜将目标图像分割成条带，再将条带按一定的规律反射到探测器的不同位置，形成不同的光谱通道。在各通道中加入分光元件，在探测器的空白区域填充光谱信息，实现三维数据立方的实时探测。相比较于传统的红外高光谱成像系统，本发明具有实时成像、无运动部件、高光通量的优点，可以实现目标的快速识别、监测、预警。
