摘要： A control system (102) operates within a dynamic range, and a follow-up system (104) is commanded to reduce a positional error between the follow-up system and the control system when the dynamic range is exceeded. A linear follow-up command may be initially provided once a dead band value (208) is exceeded. The follow-up system (104) is driven relative to its base mount (103) in a direction to reduce the positional error to within a null value range (214). The follow-up command may also implement a decay function to control the follow-up system (104). A control variable transfer function may also be utilized to gradually subtract the dead band value from the follow-up system position error command as a function of time. The decaying function may include linear as well as non-linear decaying functions. In one embodiment, a figure eight-type hysteresis control function may be implemented to control the inertial position of an inertial element. The various embodiments of the present invention may be suitable for space-based laser designating and targeting systems, space-based camera-positioning systems, space-based telescopes, and radar antenna positioning systems.

摘要： The invention relates to a system for guiding at least one projectile provided with a roll position stabilization. By means of a laser, a raster is written in a solid angle surrounding a target. An inventive timing of the raster enables the projectile to independently determine its position in the solid angle and to make in-flight corrections.

摘要： A projection system for a guide beam in which a lens (10) forms an image of a partial zone of a star target (13) turning around a rotation axis (16) which is lit by a light source (11) in a space (15), so that an object which has to be guided indicates its position in a plane which is perpendicular to the axis (17) of the guide beam, by means of the corresponding modulation frequency of the light beam of the figure. The projection system described is characterized by the fact that, in order to suppress higher orders than the first order, the separating edges between the radial beams which practically do not influence the light beam of the star target (13) and those which do influence the latter are designed so as to have a gradual outline. This offers the advantage that the pattern of intensity always exhibits simple maxima, so that the object to be guided can immediately indicate the frequency, and hence its relative position in a plane which is perpendicular to the axis of the guide beam. In a particularly advantageous development of the discovery, the gradual progression is formed by a second modulation pattern which runs in a radial direction, the local frequency of which is greater than that of the radial beams of the star target.

摘要： Mécanisme directionnel (14) destiné à être utilisé en combinaison avec un système de reproduction thermique (10). Le mécanisme directionnel comprend une paire de prismes (18, 20) placés en série en face du mécanisme de balayage (10) du système. Les prismes sont mis individuellement en rotation par des moyens moteurs (26, 30). Un codeur de position (38, 40) est relié à chacun des prismes et fournit des informations de position à un ordinateur de recherche (60) qui commande la rotation des prismes. La réfraction de l'image thermique produite par les prismes tournants permet au mécanisme de balayage (16) du système de reproduction thermique d'effectuer une recherche dans tout motif situé dans un champ de vision variable dans le champ de recherche du mécanisme directionnel (14). Le mécanisme directionnel (14) peut également fonctionner comme télémètre pour un laser (70) sur la cible visionnée par le système de reproduction thermique. Dans une forme de mise en oeuvre, le laser (70) comprend un laser à impulsions dont le faisceau est transmis par l'intermédiaire des prismes (18, 20) sur une cible. Le faisceau laser est ensuite réfléchi depuis la cible et détecté par le système de reproduction thermique. Le temps écoulé entre la transmission et la détection du faisceau laser à impulsions permet à l'ordinateur de calculer la distance de la cible. Le laser peut, en variante, comprendre un laser continu à faible puissance qui peut fonctionner comme système de désignation à laser pour des engins spaciaux.

摘要： A projector for projecting optical signals for controlling a missile comprises means for producing two alternately orthogonally scanned rectangular beams (p,y) from a single incident beam derived from a single source of laser radiation (2) and a modulator for pulse modulating said source at a plurality of pulse rates over first and second ranges of frequencies corresponding to respective ones of said two beams. The beam producing means is formed by two prism elements (14, 16) relatively movable with respect to each other by a transducer (12) to cause rotation of the beams. A Pechan prism (10) with a reversion axis oriented at 45° with respect to the length of the rectangular beam is preferred for use as the beam rotator.

摘要： The invention relates to a sighting device which is used to produce an optically perceptible target marking on an object. Said device comprises at least one light source which is used to provide two sighting rays (6, 7). The aim of the invention is to increase precision of the target marking in such a manner that both of the sighting rays (6, 7) are directed respectively onto an optical component (8, 9) enabling both of the sighting rays (6, 7) to be split on a illuminating plane (10, 11) in such a manner that both of the illuminating planes (10, 11) intersect at an angle. The point of intersection forms the target marking. The invention also relates to a device comprising a measuring, working and operating device which can be used with or without contact and which interacts with an object of all types on a predetermined target location. The target location can be detected by means of the inventive sighting device.
