Abstract
An optical sensor for detecting targets and determining the characteristic motion of a missile approaching a target. In order to have a simple designed sensor and to provide for a simple transformation of the coordinates of the missile and of the target to be determined, the optical sensor has an optical system, which, with the help of a semitransparent mirror, forms an image of the scene lying within the field of view of the optical system onto two detectors. The first detector is a planar detector having a plurality of detector elements disposed in a matrix arrangement, onto which the scene is sharply imaged, whereas the second detector is a cross detector, which is configured outside of the focal point of the optical system. With this detector, the spatial and time derivatives of the light intensity incident on the optical system and, from it, the characteristic motions of the missile are determined.
