Abstract
The present invention relates to a method for optically marking an elongated indication path. This method is comprised of supporting an optic sieve (1) along an exposed indication path, and aligning an end (4) of the optic sieve (1) (or networks of sections of optic sieves) with a light source (2) (or light socket harnessing the collective outputs of a plurality of light sources). The optic sieve (1) in the context of the present invention is characterised by having at least one side emitting optic fiber within a flexible semi opaque holographically grooved sleeve. The present invention also relates to devices having optically marked elongated indication paths according to the method of the present invention.
