The invention discloses a double-wave-band double-visual-field infrared optical system and an imaging method thereof. The double-wave-band double-visual-field infrared optical system comprises a beam splitter which is at an angle of 45 DEG to the horizontal direction. A double-lens turning mechanism which is used for changing the direction of a visual field is arranged in front of the beam splitter in an optical axis direction. A back imaging system is arranged behind the beam splitter in the optical axis direction. A no-focus system is arranged above the beam splitter. The no-focus system comprises a large-recessed-surface reflector, a total-reflection plan mirror, a convex-surface reflector and a small-recessed-surface reflector. The double-lens turning mechanism comprises two lenses which are parallel with the beam splitter. The invention further discloses a method for realizing simultaneous middle-wave infrared and long-wave infrared imaging in the double-wave-band double-visual-field infrared optical system. According to the double-wave-band double-visual-field infrared optical system, the scanning reflector system is utilized at the front end for realizing real-time adjustment for the wide visual field in the visual field direction, and a double-wave-band infrared detector focal lane array is utilized at the back end for simultaneously acquiring images of two wave bands and simultaneously displaying the images, thereby realizing simultaneous observation for a narrow-visual-field image and a wide-visual-field image on the condition that no optical structure is changed.
Description
technical field [0001] The invention belongs to the technical field of infrared optical imaging, and in particular relates to a dual-band dual-field infrared optical system and an imaging method thereof. Background technique [0002] Both mid-wave infrared images and long-wave infrared images have their own characteristics and advantages. Under different circumstances, different band images have different advantages. Combining mid-wave infrared imaging and long-wave infrared imaging can concentrate their respective advantages and obtain a wider range of images. application. In this case, multi-field of view can provide users with more advantages. Narrow field of view images can provide long-distance identification capabilities, while wide field of view images can provide search and localization capabilities. At this time, a problem arises. The two tasks of long-distance recognition and position recognition need to be completed independently by changing the field of view. ...
