Abstract

PURPOSE:To adjust the attitude of a fixed mirror or moving mirror in each cycle of the reciprocation of the moving mirror by calculating a correcting signal from errors in a phase difference based upon the specific position of the moving mirror and a phase difference in the best interference state and sending the signal to an adjusting mechanism. CONSTITUTION:When the moving mirror 20 moves forth, measurement data is inputted from a main photodetector 24 and when the mirror 20 moves back, the measurement data is not inputted. A magnetic proximity sensor 50 outputs a detection signal in the forward movement and backward movement of the moving mirror 20 respectively, so when a CPU 56 inputs the signal from the magnetic proximity sensor 20, the phase difference signal is inputted through an A/D converter 2 for a constant time. The correcting signal is calculated according to the phase difference signal and sent out to piezoelectric elements 34 and 36 in the period of the forward movement of the moving mirror, thereby adjusting the fixed mirror 18.
