Such resonance peaks can be observed in transmittance or in reflectance when two mirrors are placed parallel to each other and separated by a thin air spacer. By using a nov el approach, based on simultaneous processing of the data acquired for di fferent spacer distances we obtained reliable results with high resolution. Measurements were performed both in transmittance and reflectance layouts depending on the reflectivity of the mirror to be measured. The developed method allows dispersion measurements of ultraviolet mirrors and ultra-broadband mirrors spanning more than one optical octave to be performed. ?2013 Optical Soci ety of America OCIS codes : () Ultrafast measurements; () pression; () Interference coatings.
