Title:
POSTURE ADJUSTING DEVICE, MICHELSON INTERFEROMETER, AND FOURIER TRANSFORM SPECTROSCOPIC ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/172902
Kind Code:
A1
Abstract:
When a posture adjusting device adjusts an optical element to a predetermined posture, a control unit sets a target voltage value (V1a) of a driving voltage (V111) to be applied to a piezoelectric element in response to a posture adjustment signal. In addition, the control unit controls a driving unit so that the driving voltage (V111) to be applied to the piezoelectric element is once set to the maximum voltage value (Vmax) or the minimum voltage value (Vmin) from a current voltage value (V10) and then set to the target voltage value (V1a). The posture adjusting device can accurately and simply adjust the optical element to a predetermined posture.
