The imaging spectroscopy technology can obtain the spatial and spectral information of the observed object, and effectively distinguish the material composition of the object surface. It is widely used in the military and civilian fields. In recent years, the imaging spectroscopy devices based on filter arrays have received extensive attention due to their compact structure, fast imaging speed, and large coverage band. As a core component to determine the spectral performance of such devices, the filter array is a research hotspot. In this paper, by summarizing the main progress of spectral filter arrays, the advantages and disadvantages of different spectral filter arrays and their application range are analyzed, and the development trend of spectral filter arrays is prospected.
