Abstract
A video system is disclosed having a weapon-mounted video camera (12) transmitting video signals to a remotely located video display (14). The video display is mounted to the helmet (40) of a soldier (36), and includes a sight reticle (50) superimposed on the image of the target (46) so that the soldier (36) can aim the weapon (38) by moving it until the target object (46) as displayed by the video display (14) is aligned with the sight reticle (50). A low probability of transmission interception of the video signals is accomplished by using a nonvisible light carrier wavelength in free space, which wavelength is characterized by a high degree of absorption due to atmospheric water vapor.
