More Information
Summary: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 sys
