An object of the present invention is not affected by the vibration of the measurement water is a simple device configuration for performing the measurement of the thickness distribution with high accuracy. In the present invention, the object to be measured reflects the water (1) of the measuring points (1a, 1b) facing reference to Q2 Q2 a bimgwang again the outgoing light of the laser light source (2) and opposite front and back each other with respect to the front and back facets , obtained a non-coherent light (Pax, Pbx) as the orthogonal polarization components of the object beam and the reference beam then quarter it with a vengeance. Branch subjected to phase shift by applying the change in the phase difference between the polarization components perpendicular etc. wave plate (a261, a263, a264) with respect to one or more of the light, based on the reference light and the object light the polarization direction of the branch light after the phase shift by extracting a common polarization component of the interference light which is obtained by (Qa4 to Qa1, Qb1 to Qb4). The phase difference between the reference light and the object light of the polarization component in the non-coherent light intensity is calculated from them, the thickness distribution of the measured object (1) is calculated from the distribution of the phase difference.
