A family of straight lines can be reflected onto a surface as seen from a fixed point of vision. Curves generated in this way on the surface are called reflection lines. Deviations of the surface will give irregularities in these reflection lines. To correct these deviations, a procedure can be deve

Abstract
An acceptably dyed fabric must be a match to the target and is visually even in appearance, that is, level. Although color difference measurement can objectively determine whether a match has been achieved, levelness is still determined subjectively, leading to inevitable disagreements between dyer and customer. The levelness of a series of dyed fabrics has been objectively evaluated using a surface irregularity function derived from analysis of digital images of the fabrics. The measurements derived correlate more closely to visual assessment than do K/S measurements. © 2009 Wiley Periodicals, Inc. Col Res Appl, 34, 285–290, 2009

The technique of fluorescence labelling has been applied for the determination of functional groups on plasma and chromic acid-modified polymer surfaces. Various fluorescence dyes were coupled to carboxyl, carbonyl, hydroxyl and amino groups. It was found that fluorescence labelling is a very sensit
