Abstract: A device for jamming or damaging an enemy's infrared detection apparatus consists of the following equipment mounted on a tripod which is adjustable in azimuth and elevation: a multiple rod laser head emitting coherent light at more than one wavelength, an aiming telescope, a proximity focused image converter telescope, and an integrating image tube. The laser head is provided with a Q switch and collimating optics; the integrating image tube being adjustably mounted on the tripod so that it can be separately set for boresighting with the other instruments. In place of the laser head a generator of X-band microwave energy can be substituted.
