REGION SCANNING OPTICAL SYSTEM Russian patent published in 2000 - IPC

FIELD: thermal imaging and TV equipment. SUBSTANCE: device has mirror drum which is designed as two frustum pyramids with different dihedral angles, two-channel receiver lens, which has two first components with respect to each channel, mirrors, which are located behind it, second component, which is shared by both channels, mirror commutator, which is located in front of second component, and photodetector. Goal of invention is achieved by mirror, which is introduced in front of each first component and is positioned such as axial reflected beams are located in plane which is parallel to commutator rotation axis. Number of mirrors which are located behind first components, in channel which beams are passed through commutator, is greater by one than number of mirrors in channel, which beams are reflected from commutator. Rotation axes of mirror commutator and mirror drum are parallel. In addition device has component which is located in front of receiver and match entrance pupil of lens to cold diaphragm of receiver. EFFECT: improved of displaying real landscape image, decreased background influence to receiver caused by lens members. 2 cl, 3 dwg
