- Michelson interferometer and method for carrying out an alignment - self-test of the same

摘要

A method for carrying out an alignment - self-test - of a michelson interferometer, with the following steps:(a) placing a reference signal (12) in a reference signal path (28) of the michelson interferometer -;(b) placing of the reference signal (12) in an unknown signal path (26) of the michelson interferometer -; and(c) detecting whether the reference signal (12) according to a moving by means of the unknown signal path (26) a same period as claimed in any movement by the reference signal path (28) comprises.
