Abstract

The present invention provides a multiband flexible infrared optical system which belongs to an infrared optical system. The multiband flexible infrared optical system settles the following problems in the existing double-band optical system: narrow spectrum measurement wave band, limited optical path layout and large volume and large weight. The multiband flexible infrared optical system comprises an infrared scanning mirror, a multiband infrared lens, an optical path switching device, an optical path switching controller, an FPA interface and an optical fiber interface. The infrared scanning mirror can reflect 2-14 mu m infrared light in direction directions for coming into the multiband infrared lens. The multiband infrared lens is used for focusing the incident infrared light. The optical path switching device is arranged behind the multiband infrared lens and has a movable or rotatable structure. Furthermore the optical path switching device can perform beam splitting or time division modulation on the focused infrared light. The multiband flexible infrared optical system of the invention has advantages of: small volume, high integration degree, convenient use and high flexibility. The multiband flexible infrared optical system can be integrated in an automatic target identification system based on association of infrared image and the spectrum for realizing visual field scanning, target identifying and tracking. The multiband flexible infrared optical system is applied for infrared remote sensing detection.
