摘要：Aerial photographic-equipment of the line-scanning type in which two parabolic mirrors lie on either side of a square-section rotor with four mirror faces that reflect the scanning beam on to a ridge mirror above the rotor and by which it is directed to an infrared detector cell. The signal from the IR cell is employed to modulate a light beam at one end of the rotor, which modulated beam is reflected out radially from the rotor optical systems within the rotor so as to traverse repeatedly a photographic film which is transported above the rotor in a direction parallel to its axis.
