Title:
TRANSLATION MECHANISM, MICHELSON INTERFEROMETER, AND FOURIER TRANSFORM INFRARED SPECTROSCOPE
Document Type and Number:
WIPO Patent Application WO/2012/029453
Kind Code:
A1
Abstract:
A translation mechanism (19) comprises: a parallel plate spring structure (40), further comprising a fixed body (44), plate springs (41, 42) facing one another with a gap therebetween with one end (41a, 42a) of each said plate spring being fixed to the fixed body (44), and a rigid body (43) which connects the other ends (41b, 42b) of each said plate spring (41, 42); a drive unit (45) which causes translational vibrations in the other ends (41b, 42b) of the plate springs together with the rigid body (43); and a cantilever (50), one end whereof (50a) is fixed to the fixed body (44), and which extends in the same direction as the plate springs (41, 42). The eigenfrequency of the parallel plate spring structure (40) and the eigenfrequency of the cantilever (50) are approximately identical.
