| Abstract: | In this paper we describe a new simple interferometric method for measurement of the thickness of a very thin quivette filled with absorbing liquid. The method is based on the interferometric restoration and analysis of both p- and s-components of the attenuated totally internal reflected (ATIR) field. Two different liquid samples were studied experimentally. The interferometric signal obtained by measurements is compared with the theoretical prediction. |
