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.
