Application of FORJ Technology in Photoelectric Tracking Equipment

Abstract:

In the design of the photoelectric tracking equipment, to realize the connection between the fiber that rotates with the tracker and the fiber that fixed in the non-rotating vertical axis, The fiber optic rotary joint (FORJ) technology has been applied, which makes the optical signal be transmitted correctly under the fiber rotating status. The normal method that applying the double-channel FORJ has been introduced, based on which, a method applying single-channel FORJ and double-direction optical module has been carried out to improve the transmission quality and simplify the design structure. The insertion loss of the applied FORJ is less than 2dB and the maximum rotary speed can be up to 1000rpm. Meanwhile the design of the optic channel realizes the double-direction signal transmission with rotating movement in single route fiber. The real work shows that the signal of the equipment can be transmitted correctly.
