Scanner

An aerial vehicle rotating in gyroscopic fashion about one of its axes has an optical system which scans an area below the vehicle in determined relation to vehicle rotation. A sensing device is provided to sense the physical condition of the area of scan and optical means are associated to direct the physical intelligence received from the scan area to the sensing means. Means are provided to incrementally move the optical means through a series of steps to effect sequential line scan of the area being viewed keyed to the rotational rate of the vehicle.

Earth observation from geostationary orbit

The paper describes a number of satellite-borne infrared spin-scan sensors and discusses the operational requirements for which they were designed. The sensors considered are the spin scan cloud cameras of ATS 1 and 3, the SMS/GOES visible-infrared spin-scan radiometer, and the VISSR atmospheric sounder.
