A self-synchronizing optical radiation imaging device and optical delay circuit is provided with optics for receiving optical radiation and directing the radiation to an optical image delay system for delaying the optical radiation for a predetermined length of time. An optical radiation energy detector detects when optical radiation of a predetermined energy level has been received and actuates a gating circuit, which in turn, turns an image intensifier either on or off, depending upon the embodiment used, to coincide with the reception of the delayed signal by the image intensifier and to maintain the image intensifier on or off during the period that the receiving optics is receiving optical radiation of at least the predetermined level. An optical delay system is provided in which a bundle of incoherent fiber-optics of predetermined length are mounted to receive a signal at one end and a reflecting mirror is mounted to the opposite end for reflecting the received signal back through the bundle of fiber-optics.
