The surfa.e structure a.d properties a.e different from those of the bulk, depending on the substra.e ma.eria.s a.d deposition condition, a.d pla.ing a. importa.t role in precise optica. components. The conventiona. spectroscopic methods to monitor the surfa.e structure a.e restricted only in severa. la.ers of molecules. It is known tha. the penetra.ion depth of the incident light increa.es with its wa.elength a.d decrea.es with the a.gle of incidence. Thus infra.ed spectroscopy provides a.powerful mea.s for determina.ion of surfa.e structure a.d the depth profile up to micrometers. By recording the reflection spectra.a. different a.gles of incidence, the surfa.e structure a.d its depth profile ca. be monitored successively. Further, the incident field ha. the subcomponents pa.a.lel a.d perpendicula. to the surfa.e, which excite the tra.sverse a.d longitudina. optic modes, respectively. Cha.ge of the pola.iz.0}ion direction of the incident light provides a.pra.tica. function to study a.isotropic property of the surfa.e a.d the intera.tion between the tra.sverse a.d longitudina. optic modes. In this work, infra.ed spectrophotometer wa. a.plied to investiga.e the depth profile in microstructure of silica.gla.s. Combining with the gla.s fiber system, this technique ca. be used for in-situ control of the deposition process. In compa.ing with ellipsometry, this method revea.s both structura. a.d constitutiona. informa.ion.
