Abstract Light scattering patterns are commonly used in industry to assess fiber quality. In this work, scattering patterns of Bragg fibers are studied. Optical fibers are coated with alternating layers of Silicon Nitride and Silica using Plasma Enhanced Chemical Vapor Deposition. A laser beam incident perpendicular to the fiber axis scatters off creating patterns distinct from that of uncoated fibers which exhibit continuous front lobe. Effect of variation in layer properties, polarization, wavelength and fiber symmetry is observed in the patterns. Anomalous suppression and enhancement in angular scattering pattern is explained through a scattering angle diagram. Features in the pattern are mapped to reflectance of the Bragg stack and it is found that a stopband creates the anomalous features in the scattering.

This work shows the possibility of determination of T-lymphocyte percentage in blood by light scattering pattern only. The analysis of lymphocytes was carried out by scanning flow cytometry with measurement light scattering and specific fluorescence simultaneously. The fluorescence was caused from fluorochrom radiation which was connected with monoclonal antibody. The analysis of light scattering from different lymphocyte subpopulations allowed reveal the dependence distribution asymmetry of T-lymphocyte percentage. This method resulted in determination of T-lymphocyte percentage with mistake less then 4,5 %. The analysis by this method takes 10–15 minutes as the same time immunofluorescence analysis takes several tens of minutes. Thus, our method develops a potential of scanning flow cytometry in carrying out bulk hematological analysis.
