ABSTRACT:
A method and apparatus for determining binder dosage and distribution on a substrate. The apparatus employed is made up of:a) a source of long wave ultraviolet light positioned so that ultraviolet waves emitted therefrom will come into contact with a substrate to which binder has been applied,b) a filter which blocks ultraviolet waves emitted from the UV source and reflected by the substrate but which allows visible light waves emitted by fluorescence of the binder to pass,c) a lens for imaging visible light onto a focal plane,d) a video camera positioned at the focal plane of the lens which converts the visible light waves that have passed through the filter and the lens into an electrical signal, ande) a device capable of correlating images received by the video camera to binder dosage and distribution on the substrate contacted by the ultraviolet waves emitted by the UV source.
