OPTICAL SCANNER Russian patent published in 2000 - IPC

Abstract RU 2158948 C1

FIELD: optoelectronic instrument engineering, in particular, instruments used for spatial movement of light beam, at which the preset zone is successively "looked through", and applicable for use in infra-red imaging systems. SUBSTANCE: the scanner has an objective lens and two mirror truncated pyramids connected by smaller bases, in which the faces of one pyramid are optically matched with the objective lens, and those of the other - with the multi-element photodetector. The tilt to the axis of rotation in the circumferential direction of each face relative to the previous one differs by a constant value; for faces from the first one to N/2+1, where N - the number of faces, the tilt of the faces is made in one direction, and for the other - in the other direction. EFFECT: reduced overall dimensions of the system due to the fact that the claimed scanner makes it possible to plot two complete frames per revolution. 3 dwg
