Correlation imaging based on compressed sensing theory is a projective measurement of the signal using a measurement matrix that is uncorrelated with the sparse expression base of the signal.The measurement matrix and detection data are then used to reconstruct the hyperspectral image by computational imaging.Therefore,the measurement matrix must be obtained by calibration using the compressed sensing imaging system for spectral imaging.In this paper,a set of hyperspectral correlation imaging calibration system is built,and the design of thin film devices in the hyperspectral correlation imaging calibration system is completed through the interference cut off filter.K9 glass is selected as the substrate material,and tantalum pentoxide (Ta2O5)and silicon dioxide (SiO2)are chosen as high and low refractive index materials.According to the basic theory of optical thin films,the design of the film layer is realized by combining with the Essential Macleod film system design software.The film is prepared on OZZSQ900 box type vacuum coating machine,the reflectivity in the range of 350～380 nm is 99.61% and the reflectivity in the range of 400～740 nm is 0.98% by Lamda1050 spectrophotometer.The research has important practical significance and engineering value.
