Title:
OPTICAL PATH CORRECTING DEVICE, INTERFEROMETER, AND FOURIER-TRANSFORM SPECTROSCOPIC ANALYZER
Document Type and Number:
WIPO Patent Application WO/2011/135943
Kind Code:
A1
Abstract:
Disclosed is an optical path correcting device (31) which has a reflecting mirror, a rotating member (51), a piezoelectric element (52) as a displacement member, and a connecting member (56). The rotating member (51) has a supporting surface (51a1) that supports the reflecting mirror, and the rotating member can rotate with the rotating center (P) at the center. The piezoelectric element (52) is provided on the side opposite to the reflecting mirror with respect to the rotating member (51), and the piezoelectric element can expand/contract in the direction wherein the distance between the rotating member (51) and the piezoelectric element changes. The connecting member (56) connects together an end surface (52S), which is perpendicular to the expanding/contracting direction of the piezoelectric element (52), and the rotating member (51). The connecting member (56) has, when viewed from the expanding/contracting direction, an operating region (56a), which transmits the expansion/contraction of the piezoelectric element (52) to the rotating member (51). The operating region (56a) is narrower than the end surface (52S) of the piezoelectric element (52), and the operating region corresponds to a partial region (52S1) of the end surface (52S), said partial region being close to the rotating center (P) of the end surface.
