For passive range metering of moving vehicles a receiver is used having two detectors spaced apart and directed to the path of the vehicle which moves with constant speed and the length of which is known. The receiver measures the pass-through time of the image of the vehicle through the first detector and furthermore measures the traveling time of the image of the vehicle from one detector to the other. The distance E can be calculated by equation ##EQU1## wherein f is the focal distance of the receiver optics, Q.sub.t is the quotient of the measured time values, l is the length of the vehicle.

Optoelectronic system for passive range metering

A re-securable mine including a triggering or ignition circuit which is actuatable through the intermediary of a trigger securing arrangement. A re-securing block with a comparator is provided for a pregiven information or code and for an introduceable information or code, so as to reset the securing arrangement into the secured position at a pregivable relationship between the two informations or codes.

An infrared simulator serves to directly transduce electron beams into infrared radiation. To this purpose a modified cathode-ray tube is provided which includes an infrared transmissive window. Behind this window a film within the vacuum of the cathode-ray tube is arranged in order to transduce the electron bombardment into infrared radiation.
