ABSTRACT:
The method and apparatus for providing an elongate linear continuous, uniformed, diffused lighting environment for use in conjunction with an electronic line scanner, a photo-copier or a machine vision system, particularly for inspection and reproduction of specular surfaces such as documents or art work containing highly reflective areas on the surface thereof and other shiny surfaces. The linear illumination device includes at least one elongate source of light, illuminating a primary diffuser, to provide a primary diffused light source and a secondary elongate source of light illuminating a secondary diffuser to provide a secondary diffused light source supplied substantially along an observation plane of the illumination device. The two sources provide uniformly diffused lighting of an elongate strip of an object located at the object observing location to facilitate accurate viewing of a desired elongate portion of the object to be observed.
