ABSTRACT:
A multichannel connector for transmission of optical signals between a number of input and output channels through a rotating interface is described. The connector comprises an input and an output platforms rotating around their common axis and an optical system connecting input optical signal channels to output optical channels independent on relative rotation of the platforms. The connector conserves both the amplitude and phase of the optical signals transmitted between the input and output channels. The optical system comprises either a combination of lenses and prism rings or single computer generated hologram. It can be used, for example, for connection between input and output bundles of optical fibers through a rotation interface without cross talk of the optical signals. The connector can find important industrial, military and medical applications where the optical signals from a number of channels are to be transmitted through rotating junctions.
