The performances of complex interference filters meets today to exigent specifications and permit to enhance the physical limits of optical instruments in which they are integrated. During the manufacturing of a filter, it is obviously important to monitor with very high accuracy (typically sub-nanometric) the thickness of the deposited layers. This requires the use of an in situ measurement of the optical characteristics of the multilayer during the process.In the framework of this thesis, we have developed a new optical monitoring system which makes possible to achieve the simultaneous measurement of the transmittance of a multilayer filter, on one hand at a single wavelength defined by the user in the spectral range between 350 nm and 10...
