SCANNING SYSTEM Russian patent published in 1997 - IPC

FIELD: optoelectronic engineering. SUBSTANCE: scanning system has radiation receiver 10, transmitting objective 7, rotating polyhedral mirror drum 6 performing the horizontal scanning and positioned between transmitting objective 7 and radiation receiver image formed by it. System has concave spherical mirrors 5, mirrors 3 and 4 installed at angle to optical axis, and flat mirror 2 in entrance pupil 1 responsible for frame scanning. Drum axis of rotation is set so that trajectory of movement of radiation receiver image is concentric to concave mirror and is positioned in its focal plane. One of components of transmitting objective 7 is made as lens. Lens axis of symmetry is parallel- shifted relative to optical axis of transmitting objective in meridian plane. One of mirrors installed at angle to optical axis has cylindrical reflecting surface, cylinder axis being in sagittal plane. EFFECT: more effective design. 8 dwg
