专利汇可以提供Optical scanning equipment专利检索，专利查询，专利分析的服务。并且An aerial infra-red line-scanning system is provided in which rotation of a scanning rotor not only scans the terrain below the aerial vehicle and reflects the scanning beam on to an infra-red detection cell but also traverses a plurality of recording beams widthwise in succession across a film record transported close to the rotor in a direction parallel to the rotor axis. The recording beams are modulated in accordance with the signal output of the IR cell. The film is constrained, in the region where it is scanned by the recording beams, to a widthwise curvature centered on the axis of the rotor.，下面是Optical scanning equipment专利的具体信息内容。
1. A scanning and recording system to be carried by a vehicle, comprising a scanning rotor mounted to rotate about an axis parallel to the direction of motion of said vehicle and having a plurality of reflecting faces, detection means receiving beams reflected from said plurality of reflecting faces and giving a signal output that varies in accordance with beam strength falling thereon, record medium transport means transporting a record medium band along a path extending parallel to said axis of rotation and close to said rotor, recording beam projection means mounted on said rotor to rotate therewith and projecting at least one recording beam radially with respect to said axis of rotation which recording beam passes repeatedly widthwise across said record medium band transported close to said rotor as said rotor rotates, means modulating said recording beam in accordance with variations in the signal output of said detection means, and means constraining said record medium band, in the region of its travel where it is scanned by said recording beam, to a widthwise curvature centered on said axis of rotation.
