FIELD: scanning IR-image device. SUBSTANCE: scanning system has multiface mirror objective 1 with axis of rotation 2, two-component objective of receiver 3 with two first components : the first component 4 of the first field of view and the first component 5 of the second field of view, and the second component 6. Optical axis 7 of one of the first components 5 is brought into coincidence with optical axis 8 of the second component 6 and disposed at an angle to sight axis 9 relatively center 10 of entrance pupil 11. Optical axis 12 of component 4 is disposed at an angle to the same sight axis, broken by flat mirror 13 and brought into coincidence with optical axis 8 of the second component 6 due to mirrors of perforated disk 14, which has axis of rotation connected tightly with axis of rotation 2 of drum 1. EFFECT: improved efficiency of operation. 2 cl, 4 dwg
