Interferometer actuator
First Claim
1. A method for the movement of at least one movable means of an interferometer relative to the body of the interferometer, comprising:
- arranging at least three interferometer piezoelectric actuators, wherein said at least three interferometer piezoelectric actuators are arranged to be operated individually, so that the at least three piezoelectric actuators are capable of moving the at least one movable means of the interferometer;
activating at least one of the at least three interferometer piezoelectric actuators to operate in parallel, thereby moving the at least one movable means of the interferometer with a stroke length of at least 10 μ
m; and
activating at least one other of the at least three interferometer piezoelectric actuators to control the tilt of the at least one movable means.

Abstract
The invention relates the movement of at least one movable means of an interferometer relative to the body of the interferometer. The system according to the invention, comprises at least two interferometer actuators, that can be operated individually, so that the at least two actuators are capable of moving the at least one movable means of the interferometer. When activating at least one of the at least two interferometer actuators the at least one movable means of the interferometer is moved with a minimum need for correcting for e.g. tilt. In a preferred configuration the system and the method according to the invention comprises three interferometer actuators that can be operated individually.
