摘　　要：Binary optical element (BOE) is applied to infrared hyperspectral detector. A new type of infrared hyperspectral detecting image system is designed based on the characteristics of abun-dant color-dispersion of BOE, and an example of combining refractive-diffractive zoom optical sys-tem with Cassegrain system is presented. The system not only has simple structure, long back-working distance and few requirements for material but also can increase the image resolu-tion, abilities of accepting ray energy and registration. Consequently, by adding an appropriate stare array detector to the system, the detecting precision can be raised.Binary optical element (BOE) is applied to infrared hyperspectral detector.
