摘要： Disclosed is a method of monitoring planar sections of material having generally parallel crimps, the material having a longitudinal dimension extending generally perpendicular to the crimps and a transverse dimension generally parallel to the crimps. The material, such as a bundle of crimped fibers or tow, generally defines a plane, and the method comprises(a) illuminating the material along a line generally longitudinally of the material and over a plurality of the crimps by causing a plane of light, or the plane defined by sweeping a ray of light, to intersect with the surface of the material at an angle of between about 30.degree. and about 60.degree. with the plane of the tow when viewed along the tow band, such that the light intersecting the crimped material produces a generally zig-zagged line of illumination when viewed from an angle other than that of the light source, the peaks and valleys of which illustrate the profile of the crimped material, and(b) recording the pattern of the generally zig-zagged line from an angle relative to the material different from the plane of light such that the profile of the material can be determined.

摘要： Methods and systems that compensate for the lateral chromatic dispersion and lateral shifts induced by the propagation through a switching/routing optical system. Utilizing the methods and systems of the present invention, an output of a switching/routing optical system that produces angularly dispersed output beams is achromatized by, first, deviating the output optical beam to a direction sufficient to induce lateral chromatic aberration of the opposite sign to that produced by the switching/routing optical system; and, then, re-deviating the deviated output optical beam to a predetermined direction, where a path length of the deviated output optical beam is a length sufficient to substantially compensate the chromatic dispersion induced by the switching/routing optical system.
