- The brightness distribution across a fiber image, formed under diffuse illumination with various source geometries, has been calculated and compared with experimental observations. Brightness distribution can be modified by masking the light source to enhance or suppress selected features of the image. This technique may be regarded as a form of optical processing that could be used in conjunction with conventional image processing methods to obtain information about dimensional properties of fiber assemblies. Examples illustrate the enhancement and suppression of images formed by an assembly of colorless wool fibers; the first case has application to the measurement of fiber dimensions and orientation, while the second can be used to improve the detection of colored fiber contaminants in an assembly of colorless wool fibers.
