An optical and electronic unit records a spectral interference pattern between combined light fields. A controlled dynamic phase shift between the sample and reference light field is introduced during signal integration. A detector synchronizes introduced phase shift such that sample signal or sample interface moving at an arbitrary velocity is detected by phase change without depending on signal detection rate.patentUS2010141956EP2122299WO2008087613WO200808761339620064
