PURPOSE: A device using polarized lights for measuring a 3D shape and thickness is provided to simultaneously obtain a surface shape and the thickness information of a target object by using the polarized lights. CONSTITUTION: A device(200) using polarized lights for measuring a 3D shape and thickness comprises a white light source(210), a first beam splitter(220), a linear polarizer(230), a second beam splitter(270), a mirror(280), and a spectroscope(290). The first beam splitter sorts white light incident from the white light source into reference lights and measurement lights, thereby irradiating the same respectively to a reference mirror(240) and a measurement object(260). The first beam splitter interferes in the reference and measurement lights, which are reflected by the reference mirror and measurement object, thereby generating coherent lights. The linear polarizer linear-polarizes the reference lights so that the reference lights have only first polarizing components.

The first spectroscope generates a first coherent signal, thereby obtaining the basic shape data of the measurement object. The second spectroscope generates a second coherent signal, thereby obtaining the matching data for correcting the measurement errors of the basic shape data.
