To conform cylindrical guides is necessary bend the film to guide the light, changes induced by curving the film give rise to deformation shifts. Light losses affected by deformation has been experimentally evaluated and numerically analyzed. The effect of deformation in prism angle is specially increased for CPLG of curvatures higher than 20 m-1. An experimental method for accurate transmittance measurements related to bending is presented.engjournal articlehttps://www.osapublishing.org/col/home.cfmopen access535.36TestingPrismsTotal internal reflectionImage analysisÓptica (Física)Óptica no líneal2209.19 Óptica Física2209.13 Óptica no lineal
