METHOD FOR SYNCHRONIZATION OF THE FILM TRANSPORT VELOCITY WITH THE IMAGE VELOCITY IN A SLOTTED AERIAL CAMERA,

Abstract

The method of synchronizing the film transport rate in a slotted aerial camera with the rate of image movement is distinguished by the fact that in order to automatically eliminate the effect of errors in the operation of the transport mechanism of the camera, impulses are recorded on a magnetic track applied to the edge of the aerial film. These impulses are readout by means of magnetic heads and compared in a signal comparison block with signals entering from an image rate sensor (as a function of height and flight speed for each moment of time). A command signal from the comparison block controls the rate of the transport mechanism motor. (Author)
