A photo-reconnaissance system in which the landscape is photographed on film. The film is then developed and scanned by electro-optical sensors. The output signal from the E-O sensors is transmitted to a ground station where it is demultiplexed and displayed on a plurality of television type monitors. An operator can view the reconnaissance scene in near-real time and transmit commands back to the airborne station directing a change in flight course or a magnification of a particular target. A permanent record of the reconnaissance scene can be obtained either from the on-board film or by making a print from the television type monitors.

A method of performing aerial reconnaissance missions from an airborne station, said method comprising the steps of: photographing a scene on film with a camera having a wide angle lens, with a field of view having a long axis transverse to the direction of flight; developing said film; reading said developed film using an electro-optical reader and converting information found on the film to a video signal which includes dividing said field of view into N photo frames and converting at least a portion of each photo frame into a video frame; the electro-optical reading means being controllable to select a particular location of a frame of said film of a particular size for full video frames to be displayed on a full video screen thereby resulting in an enlargement effect; transmitting said video signal to a receiver at an associated ground station; displaying said video signal at said ground station, on N video screens, with each video screen corresponding to a frame of the field of view so that the display on each screen remains motionless for a short period of time; inputting commands from an operator at each screen at the ground station, which may include commands to select a particular portion of the corresponding frame to be displayed on a full video screen; and transmitting said commands to a receiver on said airborne station.
