Abstract
PURPOSE:To simplify a control system of an interferometer, by making a drive pulse varies in the amplitude overlap three inchworms for holding a moving mirror of the interferometer to stabilize interference conditions with the control of the direction of the moving mirror. CONSTITUTION:A moving mirror Mv of an interferometer is not on the same plane and held with inchworms G1-G3 mounted on three guides parallel with each other. Inchworms H, R and V hod three corner parts of the moving mirror Mv. The guides G1-G3 are made up of two rails 1 and 2 respectively and the inchworms are held slidably between the two rails. The inchworms comprise clamp members 3 and 4 and a piezoelectric element 5. When the same drive pulse is applied to these inchworms H, R and V, the moving mirror Mv move parallel. On the other hand, the direction of the moving mirror Mv can be adjusted by differentiating the amplitude of the drive pulse applied to the inchworms H, R and V, thereby simplifying a control circuit.
