摘要：
In order to reduce the volume and quality of the imaging system, and to improve spectral resolution and achieve large dispersion width with large field of view. A novel modified imaging system is presented. In this system, the second fery prism combined reflection with twice dispersion, the beam passes through the prism twice to be dispersed. Therefore, the system realizes compact miniature compared with conventional one. The system overcomes the disadvantages of making convex grating and serious spectral overlapping effectively. This paper presents the results of design, the results show that the structure corrects spectral bending and spectral smiles, which satisfies the requirements of airborne imaging spectrometer.
