Abstract
An image motion compensation arrangement for a TV sensor system having an image intensifier section and a camera tube section, and which moves at a velocity V over a target area at an altitude H. An electron image of the viewed scene is accelerated between electrodes in the image intensifier section and a deflection coil is added to deflect this electron image. The coil is provided with a signal such that the deflection velocity is proportional to the ratio of V/H. With automatic light control provided, the deflection signal is also made a function of a control signal which controls a high voltage power supply to the accelerating electrodes.
