摘要
The multiple channel fiber optic rotary joint of this invention can transmit an increased number of optical signals simultaneously through the de-rotating mechanism without increasing the size of the de-rotating mechanism. It also allows for the recapturing of the signals with relative ease. This is accomplished through the use of an optical condenser and/or an optical expander that reduces or expands the overall all beam structure without significantly altering the relative structure. The expanders and condensers are inverse structures in that if an optical signal is condensed when passing from right to light through the condenser it is expanded when passing left to right through the same condenser.
