AN/MSG-3A Optical Slip Ring Assembly.

Abstract

An optical slip ring assembly was developed to transfer data, but not power, on any gimballed mount, such as radars, launches, or guns. The data, analog or digital, modulates the light from light-emitting diodes. The resulting optical signal is transferred across an air gap between the stationary and rotating portions of the mount. Such a system eliminates ground loop and RF noise, and, because there are no mechanical contacts, the problems inherent in mechanical slip rings. A two-cahnnel system was demonstrated on an AN/MSG-3A radar, and an analog channel capable of a video transmission of 10 megahertz was also demonstrated. Two alternate schemes for optical coupling are also discussed. (Author)
