Description
Summary:The present article studies the optical properties dependent on wavelength and temperature for polyester PET and polyamide PA surgical suture fibers by interferometry. The polarizing Pluta interference microscope was used to investigate the changes of the optical and structural properties at different wavelengths and temperatures. The resulting data were utilized to calculate the spectral dispersions and some structural properties such as Cauchy’s dispersion constants, the resonant wavelength, the oscillation energy, the dispersion energy, the optical permittivity and the dielectric susceptibility for PET and PA sutures with different wavelengths at room temperatures. Relationship between the optical parameters with different temperatures at constant wavelength of PET and PA suture fibers were given. The variation of refractive index, isotropic refractive index and birefringence profile were measured at different temperatures.
