Abstract : Simultaneous transmission of several off-axis Gaussian beams through a lens-type beam waveguide is subjected to distortions caused by diffraction at the lens apertures and by imperfections of the lenses. The report is concerned with the diffraction effects which are inherent to the performance of beam waveguides and independent of the technological progress in producing high quality lenses. Theoretical information on the diffractional distortions of off-axis beams and the resulting cross talk is presented and numerically evaluated for typical examples. (Author)
