In a video imagery device, the detector is mounted on the missile structure and not on a head which is stabilized by gyroscopic action. The device includes optical deflection elements for bringing the stabilized optical receiving system into a position corresponding to the axis of the detector. These optical deflection elements utilize the path of the mechanical axes of rotation in elevation and in azimuth which pass through the center of the gimbal suspension. The device can be equipped to compensate for image rotation produced at the level of the detector.

A video imagery device comprising a support means for a unit constituted by a receiving optical element for focusing the radiation on an image detector rigidly fixed to a support means, a gyroscopic assembly having two degress of freedom for stabilizing the receiving optic axis, said assembly being constituted by a gimbal suspension provided with two mechanical axes of rotation which pass through its center in order to produce angular displacements in elevation and in azimuth and to cause spatial rotation of the optic axis relatively to a reference axis associated with the support means and terminating at the detector, an optical deviating means for bringing the direction of the optic axis into a position corresponding to the reference axis, said gimbal suspension and said optical deviating means being so determined that the optical deviation path passes through a first mechanical axis of rotation aforesaid and then passes through the second mechanical axis of rotation via the center of the gimbal suspension.
