Abstract
Signals, especially short pulses, are transmitted by way of a series of aligned light guides with internally reflecting boundaries (i.e., fibers or foils), with interposition of two identical transparent bodies of positive refractivity between confronting guide ends. The cross-section of each refractive body in a common longitudinal plane of symmetry of the guides consists of two symmetrical truncated lens profiles whose boundary lies on a common centerline of the adjoining guides, the optical axes of the two lens profiles lying on opposite sides of that boundary.
