ABSTRACT:
A night vision device includes an image intensifier tube for providing an intensified image of a dim or night-time scene. The night vision device also includes provision for full duplex transmission and receipt of voice audio between the user of the device and another person who is using a substantially identical device. Another provision of the device is for interrogating IFF (identify friend or foe) units worn by other personnel. The IFF units have provision for receiving a beamed interrogation signal and for transmitting a coded identification signal in response. Thus, a user of the night vision device can identify friendly personnel at a distance, as well as communicating by voice with others who are using similar night vision devices so equipped.
