Abstract: Special multiplexing of a plurality of N beams in a beam transmission system comprising a sequence of confocally spaced lenses is accomplished by directing the beams such that p separate groups of q beams are formed at odd lenses in said sequence of lenses, and q separate groups of p beams are formed at even lenses in said sequence, where p and q are integers greater than one and p X q N. The beams are resolved at the output end into N separate beams. A similar arrangement can be employed using nonconfocally spaced lenses or a continuously focusing waveguide.

Abstract: By operating a folded (cavity) delay line in a mismatched mode, it is found that the delay time can be increased by decreasing the distance between the cavity mirrors. The cavity parameters are given for optimum delay. To compensate for the mirror losses produced by each reflection, some means for producing gain is advantageously associated with the delay line.
